PRS MT15 - The Best Rock Lunchbox Guitar Amp?

[@NevermindTheNirvanaTributeBand]

Owned one for 2.5-3 years! Unbelievable amp!

[@marktullo35]

Another video clip found that this amp actually puts out about 25 watts...I bought one last year and just love the little beast! Great demo clip guys!

I like the lights also. Plus I get better tone with the lights! 😊

[@saadshah7857]

I had no idea Paul could shred those sextuplets with alt picking like that. Wicked!

[@steviesedge]

Absolutely insane tone on that overdrive channel.

[@TheStudioRats]

I was really blown away with it.

[@steviesedge]

@@TheStudioRats better than the bluguitar iridium?

[@NickFabi]

Great to see this little amp is still making big impressions. I found that changing out the valves for lower gain valves really improved the head room and tone on the clean channel and tamed the distortion channel as much as you possibly can in this “high gain” amp. But once again it’s showing it to be a lot more versatile than an amp for just mindlessly “chugging” away on. Disclaimer, I only is the clean channel as a general rule as I love the real tone of the amp and prefer to embellish what is already there with a few choice pedals.

[@without_a_spark9607]

Which tubes do you suggest?

@@without_a_spark9607 Hi Olaf, sorry for the delay I will dig out the boxes and come back to you!

[@NickFabi]

@@without_a_spark9607 Hi Olaf, off the top of my head I spoke to Sean Littleton at PRS who agreed that I was good to swap out the V3 (Preamp - Lead 2nd and 3rd gain stage) for a 12AY7 and the V6 (Phase Inverter) for an 12AT7. I think the other valve I ordered was a 5751 (low gain 12AX7) which I think I put in V5 (the FX loop) but without opening the head up and looking inside I can,t recall at the moment. Hope this helps!? Also worth taking a look at the forums but I found PRS to be more than helpful with any questions I had and then it was just a case of experimenting by swapping them around

[@without_a_spark9607]

thank you so much for your detailed answer, it helps a lot. Greetings from Germany

[@TheHeroJourneys]

Glad you guys mention that you used an attenuator, I think using one is an absolute REQUIREMENT for this amp to tame the noise and the hair-trigger lead master volume when running high gain and high treble.

[@thezogs95]

Bro this tone ❤❤❤❤

[@jonni1000rr]

An absolute beast of an amp . Good job on the review. I like your dynamics, keep rocking and I'm subscribing 🤘🏻🤘🏻

[@shaharbar]

I own this little guy, incredibly great and affordable all tube monster.

[@thomasVA9707]

Hey man, im thinking of getting this but i always play at home at quite low volume, would that work with this amp?

[@shaharbar]

@@thomasVA9707 in all honesty its pretty fucking loud, you can take it down to 7W and it should do the trick. But you may want to boost it with an OD.

[@musicinsession]

How can you not like the led! Its so fucking beautiful

[@EWT423]

I bought a PRS MT15 2 weeks ago and its amazing. I also ordered a Marshall SV20H and it arrived today...and I probably send it back. Edit: I dont know why, but the Marshall needed some time to sound good. Now its awesome too and i´ll keep it.

[@NickFabi]

Funny I bought a Marshall Origin 20H and am also in two minds as despite preferring the overdriven Marshall I love the clean PRS. The head came pre-fitted with high gain valves by the previous owner which I may also tone done or just sell it as can’t justify having another head knocking around the house!

[@BenJ2827]

Wow! never considered one of these and now I'm sold!

[@fabrizioragonesi150]

Wow fantastic amps thanks for a video 💪🎸

[@StompboxMods]

Play this amp out of a Two Rock cab. Start on the low power/7w mode. Volume and master dimed. Takes on a Soldano SLO style overdrive. Cleans are ridiculously punchy, articulate and dynamic! Same with the lead channel. Nails Warren Haynes tones with a Les Paul/335! Yet if you plug this into a cab loaded with Vintage 30s, you’ve got all the classic rock and metal tones you could ask for. Everytime I plug into it I’m blown away! Covers everything, and takes on different shades of tones depending on what cab and guitar set up you’re playing. Great video guys. You’ve just scratched the surface!🤘🤘

[@MartinStephensUK]

How loud on 7watt mode? Ok in a 10x12 room moderate voile say 85db?

[@StompboxMods]

@@MartinStephensUK I don’t own a decibel reader, but on 1/2 power you can attenuate the volume to where you can talk over it and the tone still sounds good.

[@paisteplayer1040]

The red channel responds very well to pickup volume, so it can go from ac/dc to megadeth with just your guitars volume with humbuckers

[@KelsterVonShredster]

I like the lights....each to their own :-) Cool amp! Great video always from you chaps.....

[@SDisonYT]

I really like it, but was very disappointed it didn’t have reverb built in like other competing amps do.

[@BorisBidjanSaberi11]

Thats one way to start a video… fire burning 🥵 🔥

[@faridh2999]

Great review, I’m probably going to nick your settings…. 👍

[@georgefry8035]

Lol I just did the same thing!! They really had this amp dialed in better for my style than any demo I’ve ever heard. I’ve never been great at dialing in an amp for some reason. The settings worked out fantastic 🔥🔥🔥

[@cigan82]

love mine. I have a tumnus for a boost and a plexi drive mini for a different flavor. the plexi drive sounds great. Agreed on the tubesceamer though, thats why i switched to a tumnus.

[@luispaxtor2680]

Damn, that sounds good!

[@bpy4073]

Superb playing jelous.

[@hollywoodactress]

Sounds like a great amp, btw what cab did you go through or was it direct into a DAW. I used to have a Laney GH50L which I loved and found some pedals where not great with it. One pedal I wanted to use with the Laney was a Pro Co Rat but it sounded bad. However the gain in the Laney was top notch so I just used it full on. Now the only amp I have now is a Trace Elliot Speed Twin H50 (Mk2 version), which I am sad to say I haven’t played it for a long time due to lack of space at home. You guys ever tried one or remember them from the mid/late 90s.? Mine has been 100% reliable, had it nearly 20 years and bought it when no one wanted them. I think it sounds great.

[@Deric_Rocks]

Good question re the cab!

[@Lorneplumber]

65amps ventura is my lunch box of choice

[@paisteplayer1040]

You can black electrical tape over the leds if you dont like them. Its really for onstage you can quickly see what channel you are in. The MT15 is the best lunchbox amp made under $1000

[@rileyioacura]

I would love to see your take on the new PRS HX50/100 amps (Paul reed smith and his amp technician got the chance to open up Jimi Hendrix’s main touring/gigging amp in 2018 and see all the mods and all the parts of the Marshall and has recreated it with permission from the Hendrix Family/Foundation, so it’s an official licensed reissue of the Marshall that Hendrix used)

[@TheStudioRats]

I’d love to get my hands on one of those

[@Deric_Rocks]

Great playing Paul! Nice sounding amp, weird they separated the Lead channel Volume from the rest of its controls, how weird and unergonomic! Agree about the LEDs looking tacky, makes it look like a kid's toy. Biasing vales on that amp is going to be easy - it's got the trim adjust right on the back - couldn't be easier unless they implemented some form of auto-biasing as Bugera Infinium amps have.

[@martin-1965]

Haha yes it does have that gaming computer thing going on. Only use I can think of is as a quick visual reference when at a distance from the amp to see what channel you are on but, if you've had that much to drink that you don't know in the first place, perhaps it's time to put down the guitar and have a nice lie down :)

[@PNWGuitar]

My only question, is this amp built to last and is it rugged enough to stand up to giging and touring? Seems like it to me, and from what I've read it can be converted to 50 watts fairly easily

[@jhmusic1]

It can be converted to 50 watts but you need to replace the output transformer and redesign the power supply section to up the plate voltage to normal or "regular" 6L6 plate voltage which might call for replacing the power transformer as well. In my opinion, you really don't need to. The thing is extremely loud as is. As for durability, the thing is made completely out of metal and it's a pretty heavy amp for its size, right around 20 pounds, I'd say it's rugged enough to bring on the road

[@brianpark492]

You can gig with this head and plenty loud in a big room through a cabinet.

[@weegiebuck]

What pickups are in that tele? Oh, I also like the amp/video.

[@Dkonev1902]

Will it sound great with my PRS SE’s Tremonti and Silver Sky ?

[@79lpcustom]

Very nice video. It would be great if you guys could share the pickups being used. I have tried this amp w more 'vintage' spec pickups, at loud volumes and the bottom end gets very flubby and mid scoop becomes even more evident - and as shown - it really does not like OD pedals all that much. I have had to back up gain to about 12 oclock turn bass down to about 8-9 oclock and mid and presence almost all the way up. Granted my ears are used to hearing a beautiful JTM45, so tone expectations are high. If you could let us know if those are BKP pups or some other 'better' brand I may try that route before selling the amp. Thank you!

[@bluesdude1194]

Love the channel guys. How does it compare to the EVH 5150 lunch box amp?

[@Endlessnameless803]

Have owned/gigged with both, the MT15 obliterates the EVH LBX in terms of not farting out in the low end at high volumes and feeling like a high powered amp, like my 5150 blockletter

[@davidmills16]

The hum can be significantly reduced by changing the tube in V5 (FX loop) with a 12AU7. It can also be further reduced and will also tame the gain if you replace the V3 (gain stage) tube with a 5751 and the V6 (phase inverter) tube with a 12AT7. Tonal perfection to my ears. And quiet .. 🤫

[@rikpt]

Replaced both V5 and V6 as you suggested, taken the whole amp down about 12dB, which makes the amp considerably more usable. Master volume knob is slightly less of a nightmare. Didn't mess with V3 as I didn't want to change the gain characteristics. Thanks for the recommendation!

[@TheHeroJourneys]

@@rikptI just use a cheap passive attenuator….. or how I learned to stop worrying and love the amp

[@rikpt]

@@TheHeroJourneys honestly I tried my Weber attenuator, but preferred the tube swap. The fact the attenuator is reducing the perceived noise is just it eating your higher frequencies. Don’t get me wrong, it works but 2 tubes cost £30/40.

[@rileyioacura]

The new revamped Archon 50 is meant to be amazing also!!

[@wednesdaysdisaster2141]

Can you please thell me what pedals you are using on this video ? Is it a delay pedal ? if so please tell me with one?Thankyou!!!

[@colinmortimore218]

Where is the reverb coming from?

[@paisteplayer1040]

Supposedly it supposed to be based on a twin on the clean and bogner uberschall on the dirt channel

[@JustinP.]

What model telecaster is that? Pick ups sound good!

[@peterholyman489]

Hello Paul. Just bought a new Dgt. Guitar has 11-gauge strings fitted standard. Do you use 11's or have you changed gauge? If you did, what adjustments did you make? Thanks.

[@TheStudioRats]

Hey Peter congrats. I’ve got 10s on mine, you’ll need to adjust the intonation and possibly adjust the truss Rod then that’s it, I haven’t touched it since.

[@felinekaiju4517]

Woah!. Ive not seen paul play like that before!. Knew this thing was a beast!. Great review guys!. The clean is based on a blackface, the OD/distortion is based on a Mesa Rectifier.

[@georgefry8035]

Does anybody know if this Amp they demonstrated has the JJ5881 power tubes or the 6L6 tubes? This demo is so new I’m wondering if these are the new Power Tubes. Most of demos online are a few years old and definitely had the 6L6’s

[@StompboxMods]

5881s have more clarity on the clean channel. A little less bass, with a little more treble mids. More airiness and liveliness in the tone. The lead channel, is roughly the same. I own two of these heads one with 6l6s and 5881s. They can roughly be dialed in the same. The 5881s enhance the clean tone for sure, and it adds a brilliance to the lead channel. I was skeptical at first, but I ended up loving the tone of the 5881s.

[@xtimator]

The amp they're using has 6L6's. They stated that in the first 2-3 minutes of the video. I own this amp with 5881's and love it for clean and dirty. It's my #1 amp and I own Fuchs & Peavey's!

[@paisteplayer1040]

Love mine. Dont let the 15 watt rating foul you.. It is much more. My mesa mark V35 was not 1 bit louder.

[@johntraas1252]

Superb playing, once again! How do you feel it stacks up against the BluGuitar Amp1 Iridium edition?

[@rileyioacura]

Have you had any experience with the PRS S2 series like the Vela and S2 Standard 24?? I would love to hear your opinion!! Thank you for always making incredible content!!

[@TheStudioRats]

I haven’t Riley, but if it’s a PRS from the US factory, it’s going to be great.

[@giulianosoranno8911]

Hi, which load box did you use?

[@clairepaulkayam]

Laughing at the fact that I not only have that amp, but that exact PA speaker, although in my defence I bought the speaker for teaching fitness classes, because it went nicely with my disco lights 🙈🤣

[@jamiebriggs8277]

Of course a much better amp (I like the LEDs :)), but over here in the US it's more than twice the price of the Bugera. I would opt for any number of things before the Bugera (Katana head), but it'd be great to see if you can find something closer in price to compare

[@jamiedavies8827]

Failed to mention the aweful hum buzz when connecting anything in the loop. Tried 2 and had to return both. Gutted. Read the forums before buying this

[@clairepaulkayam]

I noticed this with a reverb pedal, but thought it might have been the pedal or my crappy power supply 😬

[@jayteesgear]

If you have a NEW Mt its probably 5881 power tubes. The clean is UHH mazing just as the Lead ch

[@metalliholic]

Mine was manufactured in 2023 and it came with 6L6

[@liys540]

still prefer the iridium although prs mt15 sounds amazing

[@GingerLeftyGuitar]

Obviously that dirt channel is insane, however the clean side came across very sterile and clinical. I wonder how it sounded to you guys in the room.

[@AUTHENTICAUTOBODY]

I agree. I have this amp and the clean channel sounds much better in person, than it came across in this video. Even my drive channel sounds much less scooped, and that is with the 3 knobs nearer to 12 o'clock. Comes down to different guitars and cabs I suppose.

[@OriginalDarkMark]

Reminds me of my MK50 a bit. Doesn't quite have the separation and definition, but probably a lot more forgiving to play. Not bad for a third of the price.

[@BrianMiller-mj4xb]

No XLR outs

[@johngudgeon7454]

Blue LEDs in an amplifier attract mosquitoes like you wouldn't believe!

[@aristocaster]

Watt is always Watt, there is no "tube" or "solid state" Watts. They are not measured same way.

[@roncarter2188]

I like an amp with a really good clean channel and I thought this amp sucked for that part the overdrive was okay. I kept mine for 5 weeks and sold it and I tried it through four different cabs so I would say I gave it a fair trial, but it wasn't for me.

[@anthonysilva5312]

The reverb kind’ve wrecked this demo

[@workdays8280]

Add additional $300 reverb and a $1000 2x12 cab then U paying close to a $3000 practice amp. U Mose well buy a $200 transistor amp correct me if I'm wrong

[@jhmusic1]

This isn't a practice amp..

[@blackie75]

It's $1400.00 aud (£760.00) in Australia at the moment, which makes it almost double the cost of a Marshall DSL20H. I love the sound, but I just can't justify the extra expense while on a budget.

[@elfieborimera3178]

But made in china.i mean how long do U think it's going to last.ive own 2 Amps from china and both broke down in Under 6 months. U don't really think there real valves do you. From cars all the way down to a god dam tooth pick. China should be band from selling on the internet
