How To Mod The Boss Katana Mini for $15 | External Speaker Connection

[@PhillipMcKnight]

Great Video as always!

[@jayguitar]

Thanks so much Phillip! So much appreciated man! Thanks for the inspiration to do this :) Have an amazing day!!! :)

[@jayguitar]

Hi Carlos, should be fine to use with an adaptor 😊 I've always used batteries - the amp is designed to work on an adaptor too so as long as you have the correct adaptor I imagine you'd be fine 😊 Have an amazing day!

Jay, this is a great example of how a "how-to" video should be done; all the important steps shown, and shown clearly, with a well-paced voiceover track. Thanks!

[@jayguitar]

Thanks so much dude! Really appreciate it :) It was a pleasure to do and I have more coming soon :) Have an awesome day and thanks again!

[@jafethuerta]

Hey look BOSS, someone just took your own product and made it better !

[@jayguitar]

Thanks man! Much appreciated :) Have an excellent day :)

[@RadityoPramAdi]

now it is time to make bass version of the Katanas!!

[@flukyreview9128]

SheepDog the next katana mini version will have the added external speaker jack and boss will increase the price to $150 from $99. But thanks to Trump’s tariffs on all Chinese products, the price will go up to $200 for the US market 😂😂😂

[@MtpJunksLive]

Whos the BOSS now???😏😏😏

[@hippopothomas1980]

for safety advise, you should put a capacitor series to the red wire after the switch to the audio jack out about 10µf (really doesn't matter what µf, just letting you know this is common capacitor you should use or this). this is to prevent overload to the speaker you are going to connect to, or else you will have a risk of blowing the fuse or worse to the other speakers.

[@hippopothomas1980]

sorry, for speaker I meant amplifier.

[@jayguitar]

Hey dude, thank you so so much for the info! I will do that for sure - much appreciated 🙏 have an amazing day!!!

[@MrGlowBaby]

Hey guys, please explain - Do you mean add a capacitor between the red positive (positive side of dpdt switch) and the output Jack? Please clarify. Thanks

[@jayguitar]

@@eusuh9380 Hey dude, I haven't actually added a capacitor - if you're using an Axial or Electrolytic cap then make sure that the negative side goes to ground and the positive to the signal wire on the jack 😊 Hope that helps!

[@LeeKirkman88]

I bought the mini then as soon as i heard it and my jaw hit the floor i said right im ordering the 100w head. Job done !

[@danmar007]

Check out Anderton's channel and widen your view of the world.

[@Diy-fever]

you could've used a switching jack and avoid the switch. I did that to my Blackstar Fly 3. One thing worth mentioning is that these little amps use "full range" drivers and already have some sort of cab sim circuit built in. When you connect them to a regular guitar cab they can lack highs that have been cut twice - by both the internal cab sim circuit and the guitar speakers in the cab....in the case of Katana Mini, it might be possible to compensate with treble knob. My Fly 3 doesn't have one :)

[@jayguitar]

Hey dude, thanks so much for letting ,me know 😊 I did consider that and then decided not to as switching jacks sometimes develop problems - wanted to have a physical switch as well, just a personal preference. Thats a really good point about the full range speaker. This one doesn't have a cab emulation going to the internal speaker, just when connecting the direct output/headphone jack. I haven't noticed any drop n treble on the Katana mini. It does have the treble control though if needed 😊 Thanks and have an amazing day! 😊

[@theohiograssmen]

Love the addition of the switch! And man does the brown channel come to life in that randall cab 🤯 was thinking you may also be able to one up this mod by putting a stereo jack or something to deal with impedance in the circuit as well. Definitely making this mod to mine soon to run through 1x12 or 2x12. Good video and love the playing as well.

[@jayguitar]

Thanks dude! Glad you enjoy it! Yeah the Brown Channel sounds so excellent through the 2x12! Sounded so big in the room! Awesome that you're gonna do a mod too - a stereo output sound be pretty cool! Have an amazing day!!!

[@purplewound]

Man, seriously my jaw dropped when i heard it straight into the interface...Such a brilliant idea, congrats!

[@jayguitar]

Thanks so much! Really appreciate it :) Fun project to do. I knew it would sound great - I was really impressed with the direct sound into the interface as well! Thats gonna be pretty useful! :) Have an awesome day :)

[@jordiumethar4963]

Jay, you will be hired by Boss to experiment with their models just removed from the factory ;-). Seriously, very good modification, simple and economical and with an extraodinary result. Always surprising us.

[@jayguitar]

Thanks so much Jordi! Oh I would so love to do that!!!!! That would be pretty cool to work with Boss. Maybe I'll speak with them when I'm at NAMM in January ;) Have an awesome day my friend!

[@stompboxcoverband9404]

First off, when you started playing Brown sound thru 2-12 at the end, terrific lead playing!!! Second thank you for a great idea and a slow video of how to do it. Lastly, I love seeing that tiny amp on top of big cabinet while you're jamming, so cool! Love your positive attitude. Have a good day till next time!

[@jayguitar]

Thanks so much man! Much much appreciated and a pleasure to show the process. Love the sound through the 2x12! Always amazes me how speakers play such a big part in the overall sound. It’s a great little mod to do 😃 have an amazing day!

[@giancarlopaolini7529]

Great ! ...so why the hell they (Boss) didn't think about this option thus allowing the utilisation of bigger speakers if needed rather than the mini onboard speaker of the amp ? One could have opted also for a dual signal chains by means of two mini amps, one routed to a 2x12' cab and perhaps the second one to a 2x10' or even 4x12' with a tc mimiq at the top of the chain feeding two slightly delayed guitar inputs thus making the whole thing a lot more interesting like a kinda wall of sound. Just wondering why ...

[@jayguitar]

Thanks man! Thats a great Q as well - usually it just comes down to cost and practicality. It would only cost a couple of bucks for Boss to implement in each amp but the you multiply that by the thousands of units that they produce, it adds up to a much bigger sum. The mini was designed to be a portable solution as well - just something that we could all plug into and enjoy on the fly, which i think it does beautifully :) And hey, its alway nice to be able to add mods and do stuff like that right? :) Enjoy and have an awesome day dude!!

[@Tank23333]

im also wondering why they dont do those things but i think it has more to do with market strategy that they try to get away as little features as they can to keep the need for higher priced gear. They also have a bigger battery powered amp with wireless guitar connection but it doesnt have a speaker out or a effects loop wich makes no sense to me and its around the price of the 100watt head

[@seanantley1965]

How awesome!!! And how funny!!! I was thinking, "I wonder if Jay has any step drill bits?" And you pulled one out haha!!! I have a set of three. One exactly like the one you used then two others with longer steps. When I got those about 5 years ago, I had no idea how much I'd use them especially for guitar repair and modding. Almost every time I do any modification I reach for that exact drill bit haha!!! Sounds amazing Jay!!! I'm absolutely positive that when I get the Katana mini, I'll do this mod. Especially since you showed the last part of being able to go direct for recording! Thank you bro!!!

[@jayguitar]

Way cool! They are so useful! I have had one for years - saves me every time I screw up drilling a hole! Haha!!! Fantastic about the mod! Let me know when you do it! Its so much fun playing this little monster through a big cab!!! :) Have an awesome day bro!

[@buck7477]

I just went from the Katana record out into my Blackstar Superfly and it has an extra speaker so now I have katana stereo sound! You can probably just go from record out to your Interface also then to Your monitors!

[@antneyfatts665]

You're the man and thanks for the tip. I just purchased the mini a week ago and I F'N love it!!

[@jayguitar]

Excellent that you got one! They re great aren't they? 😃 Glad you are digging it man! Have an amazing day!

[@Anshul1614]

thank you works great, please make a video for an effects loop next if it's possible. I really enjoy this

[@HensleyDon]

+Jay Parmar Great idea! Similar to a project on my list, yes another bit of procrastination.... [Grin] I have a little behringer ULTRABASS BT108 that I want to run into my Carvin single 15" cabinet from back in my "weekend warrior" days. (They got my amp head when I got all that other stuff stolen) Since the speakers are the same ohmage, I plan on using "a normally-closed two-lug jack for simplicity. I can just plug into the cabinet and the amp will go to the Carvin (naturally with the power off). And, as you said, I'll also have the option of using a direct box if I get far enough to ever get my hand back in enough to record again. I've got a Rogue long-scale bass still waiting for its D'Addario ETB92 Nylon Tapewound Medium Gauge Strings. I don't remember who to credit for the insight but someone once observed (I'm paraphrasing), "The amount of time available will always constrict in direct relation to the amount of things you plan to do." I've had to learn not to sweat it and prioritize, do what I can and save the rest for later. I may be retired but, with an ever expanding family, plans change from one moment to the next. The amp and the mod sound great! Kudos on the steady hands... I'd never be able to film my solder work. My hands aren't as steady as they were. That's why I decided to go with Sigler Music's "Modern ES-335" wiring for my new build, quality parts and I only have to rework whatever wiring that needs moved around. The small stuff is already beautifully soldered for me. The mini DPDT toggles for the two single-coil/double-coil and in/out phase switch for my Carvin pickups will be enough of a challenge.... As always, great vid!

[@thomasfokas]

How many ohms is the 4 inch speaker? I think my 2x12 cabinet is 16 ohms... or maybe 8? At least it’s not a tube output scared so it probably doesn’t matter as much? I guess all that matters is that the switch can’t handle the amount of output from the katana amp output.

[@jayguitar]

Hi Thomas, the internal speaker is 4ohms - my 2x12 operates at 4ohms as well so its a good match 😊 I was reading up on solid state amps and impedance loads and even with solid state, a mismatch can in the long term cause issues- but you know, its a little $100 amp so I'm not too worried myself 😊 It sounds excellent through the 2x12 and makes it a blast to play! 😃 Have an amazing day man!

[@barryloftin4159]

Hey man that’s awesome and surprised that it has enough power to push that cabinet !!! Never would have thought it man ??? Thanks Jay

[@jayguitar]

Its quite a little beast when its going right?! :) Amazing tone and yep, enough power to push that 2x12 - love playing it through the 2x12 now... Gonna be some tears when I have to store the 2x12 back in the studio soon!!! lol! Have an amazing day Barry :)

[@sparky191]

Great mod. I thought it would open up the sound a bit more than it did though. Great option though should be standard

[@jayguitar]

Hey dude, thanks so much! Thats probably the mic - I should have set up stereo mics - it sounds really cool in the room! Boss not including it probably just comes down to cost and practicality I imagine. It would only cost a couple of bucks for Boss to implement in each amp (parts and labour) but when you multiply that by the thousands of units that they produce, it adds up to a pretty big sum. The mini was designed to be a portable solution as well - just something that we could all plug into and enjoy on the fly, which i think it does beautifully :) And hey, doing the DIY thing is alway fun right? :) Enjoy and have an awesome day!!

[@raindogred]

Well done, sounds great. I just wonder with these types of mods by driving a larger load, or wrong impedance speaker if you might be causing the amp ic to overheat, thus bring it to an earlier than normal demise? One way to check I geuss would be to open it up and have a look on the main board and get the chip number ( that is, if it is a chip amp and not discrete)..then could check the specs, and see what its rated output vs voltage vs power ..they usually give the number for 2,4,8,16 ohm or specify for example it can/should only be used with say 4ohm, or 8 ohm and will put XX number of watts on YY Voltage etc. It definitely doesn't sound like theres any impedance mismatch...but you never know???

[@jayguitar]

Hey dude, thanks so much! You know, it probably does load the circuit more then it should but I kinda took a view on it - its a $100 amp so of me it was ok to do - and as long as the impedance is matched, the energy from the amp will output in the correct way and it will only ever output 7 watts total regardless of speaker size (hence their are tiny amp circuits out there) :) I measured the internal cab impedance and it was 4 ohms which is the same as my Randall cab as well so all good :) Yay! And it works well and feeds back and does all of those awesome things!!! Enjoy and have an amazing day! :)

[@mrpagliero]

Great Video ,going to try this on the katana air ...will need 2 switches and jacks.

Very nice! Thanks for the instructions. Exactly what that little bugger needed. Out of curiosity - what is the impedance of the internal speaker, or the 2x12 for that matter?

[@jayguitar]

You're most welcome :) Glad you enjoyed it. Makes such a big difference to the sound. Internal speaker (and my 2x12) is 4Ohms :) Have an awesome day Steve :)

[@jayguitar]

Thanks so much James! This was fun to do 😊 that’s a really good suggestion - I’ll do that at some point! Have a amazing day man! 😊

[@lilziggy1581]

You could do the same with the aux jack and an aux to 1/4 inch converter

[@jayguitar]

Hey dude, unfortunately that wouldn't work for 2 reasons - the Aux out doesn't send the power amp part of the amplifier to the aux output (so you would end up having to plug into an external power amp to get any volume), and second the aux output has a cab simulator on it, which you don't want when plugging into an actual cab. Anyways, have a great day 🤘

[@beakyturbot]

Why not use a switching socket so you only need the jack socket? Wouldn't plugging in the jack lead then automatically disconnect the internal speaker?

[@jayguitar]

Hey John, thats a great Q and something that I had considered - but I recently watched an episode of Tone Talk with Dave Freidman and John Suhr and they were talking about the reliability issues with those jacks and how they preferred to use standard jacks and switches if necessary, so I went with the jack and switch :) Have an excellent day man!

[@codyvenne2416]

That's awesome!! Going to have to do this mod when I finally get one.

[@jayguitar]

Thanks Cody! Way cool! Its a great little amp, I've been really impressed with it :) Enjoy and have an excellent day!

[@mlcleve766]

I just use the headphone/emulated out and run it into my peavey vypyr vip1 and my Behringer vtone 108 amplifiers CD/line in input. Works like a champ. Just use katana controls

[@jayguitar]

Very cool 😊 That works well going into an amp like the vypyr - going straight into a cab you'd need the jack so that you bypass the cab simulation and can also use all of the power amp output on the mini 😊 Have an amazing day!

[@christianbouchard7136]

Thanks dude, I will do it over the weekend:)

[@benpyman8635]

Hi Jay. Great little mod! Did you get more volume overall out of the cab than the onboard speaker? I'm guessing not since 7 watt is 7 watt, and bigger speakers require more power to drive?

[@jayguitar]

Hi Ben, thanks man! There is a perception of extra volume just because its driving a bigger speaker but its still only outputting 7 watts :) Yes the bigger speakers need extra drive but work fine with lower volumes as well - they don't start breaking up so amp does all of the work :) Hope that helps! Have an amazing day man!

[@andrewpurcell2077]

Great video...and playing! Here's a question - can the power supply be used after the conversion? or is it strictly batter power after the conversion. Thanks:)

[@jayguitar]

Glad you enjoyed it Andrew. Yes, power supply works just as usual with the mod installed. Have an awesome day!

[@jayguitar]

You e most welcome and thank you so much! Its very much appreciated my friend! Have an amazing day :)

[@hoosierdaddy2308]

Very cool. My only worry being I have so little experience and understanding about this stuff would be does it match the cab in ohms like a normal head, and do you need a speaker cab, etc?. t Thanks for sharing..

[@jayguitar]

Hi Tim, thanks so much and great point about the cab - the speaker inside is rated at 4 ohms (I think I measured correctly) and my cab is 4 as well so it matched well :) From what I have read recently about solid state amp, going above the recommended ohms of a cab will only reduce power and speaker of cab should never be under the ohms rating of a solid state. But worth checking out on the internet and doing some research :) Hope that helps. Have an amazing day!!! :)

[@iadorasjourney]

Hey Jay! Nice video and really nice sound on that little amp :) I was wondering: do you also use the 9V AC Adaptor with it or just the batteries? It's important to know this since in some other videos they claim it could ruin the amp. Thanks and happy music!

[@jayguitar]

Hey dude, thanks so much! Really appreciate it 😊 My one has been working great and hasn't had any issues with power - i have run it on batteries since I purchased and its been working fantastic either through the internal speaker or a bigger cab 😊 Hope that helps. Have an amazing day!!!

[@iadorasjourney]

Hey Jay! Thank you so much for the answer!👍🏻 Sorry I wasn’t clear in my question😬: do you use the AC Adapter with the big cabinet also? As I mentioned before some people in the tube write that it could break the amp. And I’d like to use it more with the normal current because of course, batteries are expensive at some point😌 Thanks once again and happy music!🤟🏻🎸

[@jayguitar]

That's OK dude - I still use batteries with a bigger cab. Its worked fine for me, I haven't had any issues with the amp yet so all good 😊

[@brandonbell4420]

Would it cause damage to use the 9v power supply?

[@Iam-fq5nw]

Hi Jay, that is a great mod! I love you video and your genuine excitement! I just bought Katana Mini for my daughter and I am so happy it is modable, that is just a bonus. Total newby here and I have one question: when it is powered through Roland PSB-230EU (which consists of recommended PSB-1U) it has really loud buzz on crunch and even louder on brown channel when gain is used- more gain more buzz, mire volume more buzz. Clean channel is much better but buzz is still there.Guitar is connected to the amp, buzz gets marginally quieter when I touch guitar strings or grounding screw at the back of the amp. Guitar has three single pickups. Is this normal? Do you have the same problem and if you do, how have you solved it? Your input or anyone else's would be very much appreciated. Keep on rocking!

[@jayguitar]

Hey dude, ah - noise issues! Could be a couple of things - might be the power supply itself. If the amp is quiet on batteries, then either the power brick itself, or the wall supply that you're plugging into could be introducing noise - I've experienced that myself many time. So, check if it is that by installing batteries and seeing if the noise goes away. Also check your guitar cable. I plugged in a very very very cheap cable a few days ago into one of my amps (just something that was lying around) - the amount of noise it introduced was unbelievable! Hence cable is no longer used! lol! Hopefully its one of those issues and it can be resolved. Hope that helps. Have a great day!

[@Mastercutor1995]

Hey, at first it's a great video and you win with your joy on playing guitar a new subscriber. I've got a adjustabil cabinet, wich kind of Ohm do you use, is 4 ohm enough or did i need 8 ohm.

[@jayguitar]

Thanks so much! I always love playing through this amp - its one of those pieces of gear that brings a smile :) The internal speaker is 4 ohms (i thin kI measured correctly) so you should be good to go with a 4 ohms cab. My Randall is 4 ohms also :) Hope that helps and have an amazing day!

Thanks so much man! So much fun to do 😃 I am using batteries for this one. I usually just have it loaded with batteries so that I can take it to where I need and then play it with or without an external cab 😊 Both work great - adapter will obviously keep going, batteries will eventually run out of charge. I love using batteries or battery packs though as they are so quiet 😊 Hope that helps man! Have an amazing day 😊

Great Video and great mod! I plan on doing it with mine! Question: what gage wire did you use? Does it matter? Thanks for posting great reviews!

[@jayguitar]

Thanks so much Mark :) I use 22AWG wire, which is regular guitar hook up wire (i have some in my workshop hence used it) and it worked well :) A good gauge wire will transfer the sound/signal more efficiently so you'll get the clearest possible sound. Kinda like the comparison between putting really cheap tires on a Lamborghini as opposed to expensive Michelins - the cheaper tires will work but won't transfer all the power to the road :) Hope that helps dude. Have an amazing day :)

[@FretFriendGWaL]

Good mod but there is an easier way: just install a switching jack! When you plug in an external cab, the internal speaker disconnects. BTW, you must only use an 8 ohm external cab...

[@jayguitar]

Hey dude, thanks man! that's a great suggestion - It is one that I considered before doing the mod but I decided against it as switching jacks do start to fail after a while imo and that can cause issues. So, I opted for a standard jack and switch 😊 Have an amazing day!

@@jayguitar Fair comment! Have a great day :D

[@SisterRose]

when you opened it up, did it look like there were any internal trims(or possibility of adding one) to control the delay? I'd really like to increase the repeats, and was wondering if there was an input on the PCB that could do that.

[@jayguitar]

Thats a great Q - I don't't recall seeing any. The circuit board was exposed and I just had a look at the screen shot of it and couldn't see any so I'm assuming that the delay repeats are fixed . Hope that helps 😊 Have an amazing day!

Nice video. And if i try to do this but my amp is stereo (thr10 yamaha) how i make ? Use one selector switch for 2 stereo speaker ? Or two selector switch to each speaker ? Please, aswer me. I need help in this. Thank you.

[@jayguitar]

Thanks so much man! Yes, possible to do with a stereo amp as well - you'd need a TPDT switch (3 sets of connectors) like this one - www.parts-express.com/3pdt-mini-toggle-switch--060-520?gclid=EAIaIQobChMI-dCqoubY3QIVmMDICh3dTQl9EAQYASABEgI_dvD_BwE - and then decide whether you'd want it to go to a mono signal, in which case use a mono jack (both left and right going to the mono jack) or a stereo signal, in which case you can either have two moo jacks or a a stereo jack 😊 Hope that helps. If you do do it, I would love to see it 😊 Have an amazing day.

I would be curious to see if you could even improve on power and sound quality with the help of the AMP1 plugged into this now Boss Katana " mini head " .

I imagine that my AMP1 into the Katana would blow it up! lol!!! AMP1 has a full 100 watts on tap so that would go straight into the cab - and it does sound absolutely amazing :) Have an awesome day dude!

[@kdrake777]

Couldn’t you put a 1/8 to 1/4 inch adapter on a speaker cable into the emulated out / phone jack into an external speaker?

[@jayguitar]

Hey dude, thats a great Q - you could, but you wouldn't get much output - the emulated out is a very quiet signal so I imagine you'd just about hear it - its essentially designed to go straight into an audio interface which takes a lower output signal. But Boss seems to have made it super quiet! lol! You can check out how I process it on this video - kzbin.info/www/bejne/qGHbnmlrnLGLms0 - Enjoy and have an excellent day!!! :)

@@jayguitar Jay, do you think this would work well if I plugged it into my Blues Junior or Roland Cube 30 as I don't have a cab?

[@jayguitar]

@@bungy007 Hey dude, you could probably do that using the headphone out on the Katana Mini into the clean channel on either amp. The Blues Jr and the Roland have pre and power amps built in so you'd need to be mindful of that. The speaker jack that I installed on the mini sends the full 7 watts to a speaker which would likely damage an amp if you put that into the amp so I wouldn't recommend doing 😊 Headphone jack into clean channel is probably your best bet - as the signal is stepped down and then reamplified by the Blues Jr or the Roland 😊

Hey Aron, yes you can :) plug a 3.2mm audio jack into the phones/record out on the back of the amp, attach the other end of the jack to your interface input (you will need an adapter to 6.3mm jack) and you'll be good to go. The speaker output that I created will output too much signal to the interface and could damage it so that isn't recommended. Hope that helps! Have an amazing day!

Big Arigatou from Ukraine, Kiev. Now i know what i do to my Katana Chibi :)

[@jayguitar]

Very cool! It’s a great little mod to do. Enjoy and have an amazing day!

[@1129bd]

Jay just keep it wired to 2*12 cab sounds better

[@jayguitar]

Yep, my thoughts exactly!!! lol! Its great to have both options as I can take it with me wherever I go and use it through a speak cab when I have access to one :) Win win!!!!! Have an excellent day dude!

[@brpadington]

Is there any bleed through on the internal speaker when it is hooked up to a cab? I did a similar mod and at high volumes there was a little bleed.

[@jayguitar]

Hey dude, I haven't noticed any bleed on mine. If there is bleed then my thought is that the switch is cross talking between positions. I have had that happen to me with mini toggle switches previously :) Hope that helps and have an awesome day!

[@brpadington]

Jay Parmar Thanks! I was using a toggle switch. The bleed didn't happen until months later. Guessing I had a switch degrade on me.

[@Seadogstudio]

Try a switch with bigger voltage rating, they usually are bigger and have better separation.

[@Beelzehump]

Are you sure you can use the speaker output without damaging your interface on the long run?

[@jayguitar]

Hi Peter, great point - I have been using my BluGuitar AMP1 direct out into my interface and it seems to have a similar output to the mini so I imagine it will be ok (been using the AMP1 direct for a year and a half pretty much constantly). But I do have a BluGuitar BluBox so could use it through that and then the interface :) Thanks man and have an excellent day!

[@Beelzehump]

Jay Parmar Good to know. Great content as always. Have a great day too sir.

[@SlightlyTechnical]

one thing you can do is put a lead into the output jack and measure the other end of excessive voltage with a multi meter i don't know off hand what the range is for something like this but should be able to find out

[@colefields6018]

Hey jay, Any chance you could do this with the new katana Air ?

[@jayguitar]

Hey Cole 😊 I guess you could - I haven’t seen the inside of the Air but chances are that it will be similar. Basically the connection goes between the speaker cables and the speaker 😊 I gotta check out the Air at some stage. Love the mini! Have an amazing day 😊

[@Filterbear]

Hello,canib listen music via the AUX?in Good condition

[@jayguitar]

Hey Arnaud, yes you can :) but the sound is different and the AUX won't drive a speaker cabinet in this way :) Hope that helps. Have an awesome day!

[@SC4211]

Maybe I should try this with my Blackstar Fly. I wonder what that would be like?

[@jayguitar]

Very cool idea! I would love to know how that sounds 😊 if you do it please do let me know. Have an awesome day!

[@SC4211]

@@jayguitar You know, with a good Greenback or something similar, just about anything'll sound good. I bet this'll turn out at least decent. It does make me wonder, though - can batteries handle having a speaker to power? If so, this might be something I could even busk with.

[@JMartinN]

Hello Jay' just wondering you made this mod because you wanted a 1/4 plug? I noticed on my Boss Katana Mini there's an output for "phones/rec out cabinet voiced" only thing is that it's a 1/8 jack. I used an adaptor 1/8 to 1/4 and it worked.

[@jayguitar]

Hi Martin, thats a great Q - well, the 1/8 inch jack is an emulated out so has a cab simulation and power step down built into it. Adding the 1/4 inch jack bypasses the cab emulation and sends the full 7 watts to the speaker cab that I'm using and also the recording software when I plug it in direct :) Hope that helps. Have an amazing day dude!!! :)

[@JMartinN]

Hi Jay! me again! I just did this mod today to my Katana mini and wow! this is awesome, so cool! enjoying it very much! Thanx!

[@MindFullCheeseburger]

What's the difference between this mod and getting the katana head?

[@jayguitar]

Many differences. The main one being that this is a much smaller, portable amp, runs on batteries - easy to take places, etc. It has less features then the head also, which I believe is 100 watts correct? This is 7 watts. The price difference is significant as well $100 vs $350 😊 Hope the helps. Have a great day.

[@MindFullCheeseburger]

@@jayguitar thank you for the reply! i was thinking of getting the head but I don't play at loud volumes but getting the mini and doing this mod saves a ton of cash and I can just take it in my backpack

[@peterbrusch1493]

Really great, likje all Your videos.

[@jayguitar]

Thank you so much Peter :) Really appreciate it man! Have an awesome day :)

[@djritm3215]

Whats the speaker impedance?

[@jayguitar]

If I can remember correctly it is 8ohms internal speaker - my speaker cab runs at 8ohms too. Thanks and have an amazing day! 😊 🤘

[@all1n1]

Can I do the same thing to katana air?

[@jayguitar]

Hi Allin, I imagine you can - But I haven't had any experience with the Katana Air so cannot tell you for sure 😊 Have an amazing day.

[@all1n1]

Jay Parmar Great Thanks,bro!

[@Gothguitarist]

Cut a aux cable solder it to aguitar output jack bam ;]

[@jayguitar]

Hi Joey, unfortunately that won't work as the aux is an emulated out and set up for headphones so the output is much lower and there is a cab simulation on the sound as well. This way the amp goes directly to the speaker cab 😊 Worth doing as the sound is pretty amazing!!! 😊 Enjoy and have an amazing day!!!

[@Gothguitarist]

If you use a switching stereo 6.5mm jack you can do away with the switch and it turns on when you plug a cable in. www.jaycar.com.au/high-quality-pcb-mounting-6-5mm-phono-jack/p/PS0195

Very cool man! I thought about that initially but have heard that the switching jacks can develop switching issues so stayed with the switch and regular jack. But it can definitely work 😃 Have an awesome day man!

[@arturovod5847]

I now guys from Karavaevi Dachi (Big tehnic Bassar in Kiev) they can make this for me.

[@JVJF7]

But couldn't you just use the audio out plug?

[@jayguitar]

Hi Jamie, no that won’t work as the power amp is bypassed on the audio out plug so there would be practically no volume to the speakers. It also has a fab emulation built in which you wouldn’t want going into a regular passive cab. If you’re gonna be using a powered speaker, like a FRFR speaker then yes it would work but again with the cab emulation engaged (there is no way to switch that off on the audio out). Have an awesome day 😊🤟🙏

[@bkbinj6320]

Thanks for doing this mod and making a "how to" video. Much appreciated. Of note, I saw yesterday on Dave Simpson's channel that Orange have added an 8 ohm speaker output to their Orange Mini Crush 3 watt amp. See Dave's video here. kzbin.info/www/bejne/Y3SXdoSgi6l8mqs I like the Katana Mini with your mod better.

[@jayguitar]

You're most welcome :) It was a fun project to do and hey the Katana sounds sooooooo cool through a 2x12! :) Awesome about Dave's video - I'll check that out :) These little amps through big speakers sound great! Enjoy and have an awesome day :)

[@taleofrevenge]

So how loud is it actually running at full volume?

[@jayguitar]

Hi John, it has plenty of pep - probably not loud enough to be heard over loud drums or for a full gig (unless you mic it up in which case it will be). Its a blast to play though and does seem to add a little more volume, and the bigger cab adds a nice amount of punch and low end 😊 Enjoy and have an amazing day!

[@aryabiswas1409]

What if I use a 3.5 mm jack and a quarter inch adaptor and connect a cab with the headphone jack of the Katana

[@jayguitar]

Hey dude, doesn't work as the headphone jack is set to send out a low volume signal. Also it has speaker emulation on it so that would be sent to the speaker. Adding the speaker jack allows you to send the full 7 watts to a cab, bypass the speaker emulation, and get the tone of just the amp through a cab 😃 Hope that helps. Have a grey day! 😊

[@aryabiswas1409]

Jay Parmar Then what abt the lineout jack?? It outputs the original signal

[@jayguitar]

There is no line out on the Katana mini 😊

[@hutchfromba]

The amp will fry soon because the transformer is not strong enough to drive the speaker for months and years.

[@jayguitar]

Hey dude :) I guess only time will tell :) Its working pretty good so far as the speaker impedance is matched to my bigger cab - and it only gets used like that now and then. Fun project to do though - have a mini Katana head now! yay! Enjoy and have an awesome day :)

[@brpadington]

As long as the impedance is the same its ok.

[@RadityoPramAdi]

I was about to ask this!! Great video, and man it cleans up very nicely..

[@jayguitar]

Definitely does clean up well - the analogue circuit provides that very cool touch :)Love this little amp! 😃

[@ot4kon]

No. It will fry if the impedance is lower. He said that the impedance is matched. Do you know how loud just 1 watt can be?

[@davesaenz3732]

Hi my name is Dave. I work for Boss customer service and you're warranty......well,... yeah. Gone!!

[@jayguitar]

Hi Dave 😊 Yeah I know, thats why I said at 2:55 on the video that the warranty is voided by doing the work (and mentioned it in the description box). It wasn't a big deal for me as its only a $90 amp and it added something I really wanted on it. So, I wasn't too worried about that. Anyway, thanks and have an amazing day 😊

[@davesaenz3732]

@@jayguitar I was joking Jay! I am not from Boss. But I'm sure if they see a hole on your amp they will not honor any warranty. Lol.
