BUILD YOUR OWN FEEDBACK LOOPER

[@xxstevenicholxx8732]

This is a pretty cool build. Would be really neat to add an expression pedal to change the Resistance of the potentiometer

[@HOLYISLANDAUDIO]

would super easy to add an exp jack you just need a switching stereo jack 👍

[@AzzaYaDog]

I followed this except without the DC Jack, led and resistore and I dunno if I did it right or not. When the pedal is turned off I lose the effect pedal its linked to and just get a clean sound, is this correct? Also doesn't seem to like my DIY fuzz I built as it doesn't change much but makes my Autowah go crazy when it the knob is fully to the right which is funny as

[@HOLYISLANDAUDIO]

yep it should just be a clean bypass. Some circuits will react differently to feedback loops its just the nature of the beast

[@AzzaYaDog]

@@HOLYISLANDAUDIO oh sweet guess I did it right then hahahahaha

[@MadMarcWinnipeg]

Is the power just for the led so that you know its on?

[@philspill6854]

Built one upside down with a giant knob i control with my foot. Nice!

[@HOLYISLANDAUDIO]

Rad! Best thing about using oversized knobs for sure.

[@philspill6854]

@@HOLYISLANDAUDIO how would it work with a Digitech Freqout? Have one but its not near me now

[@HOLYISLANDAUDIO]

@@philspill6854 🤷‍♂️ No idea? you’ll have to try it

[@th3rdpartyproductions98]

Killer job! Thanks

[@HOLYISLANDAUDIO]

TH3RD PARTY 👍👍

[@NikkoBalbedina]

imagine if instead of a potentiometer, you connect it to some sort of rocking pedal (like a volume or wah)

[@HOLYISLANDAUDIO]

very easy mod adding an exp out for pedal. May do a tutorial on it in the future 🤔

[@PyfeTweesen]

@@HOLYISLANDAUDIO DO IT!!!

[@kadenshoemaker6669]

​Yes please do a diy video for it

[@federico_ben]

Great vid!!! Thank you so much! Can you do a loop effect for a delay?

[@HOLYISLANDAUDIO]

yep this will work with a delay, that's basically how the feedback knob works on a lot of delay pedals.

[@lunchpin403]

This is awesome

[@HOLYISLANDAUDIO]

David Cox thanks pal!

[@Kerogas_]

I'm an absolute noob in building things like these. Can you describe the steps to add an expression pedal jack? Thank you in advance.

[@HOLYISLANDAUDIO]

you’d need a stereo switching jack, its difficult to explain in a comment with no diagrams but if you give it a google there are quite a few articles on swapping a pot for an EXP in 👍

[@digital_sea_]

Is there an easy way to add a dry and wet blend?

[@HOLYISLANDAUDIO]

You would need to build another circuit to run a parallel clean blend. The runoffgroove splitter-blend would do it I’m sure there are simpler circuits for clean blends too if you have a dig online

[@Post_war_designs]

everything is turned on but it doesnt sound like any signal is passing through with the pedal on or off? probs gonna take another crack at it tomorrow but any tips on where i may have went wrong?

[@jackdixon9742]

Working on integrating this into a modded les paul.Thanks for the tutorial 🙏🏼

[@HOLYISLANDAUDIO]

Sounds interesting! would love to see how it's ends up looking :)

[@KyleTehPirate]

do you think one these could be built into a guitar with a push-button switch? instant feedback fun at your fingers while playing?

[@HOLYISLANDAUDIO]

@@KyleTehPirate Wouldn’t really do much without pedals in the loop

[@KyleTehPirate]

@@HOLYISLANDAUDIO thanks. ya i was thinking it would be a cool idea if something like digitech freqout momentary feedback could be built into the guitar.

[@aeyaey7576]

Is this possible with a dpdt momentary and a passive? I love your pedal btw. Great work!

[@HOLYISLANDAUDIO]

Yeah man just ignore the right hand column of the 3pdt switch. The Power jack is just for the LED so will work passively!

[@bwa_8]

Nickel 👌. Merci mec.

[@gyrosphinx]

Brilliant! Thanks :)

[@HOLYISLANDAUDIO]

gyrosphinx no worries dude!

[@wrencormier513]

If I were trying to integrate this into a pedal, (so it wouldn't have any jacks, I just want the knob, the LED and the footswitch, would you just split the signal of the pedal in two at the end of the circuit, and then treat one side of that as the send and return hot leads on the jacks and the other side as the in and out hot leads on the jacks?

[@wrencormier513]

The pedal is a modified fuzz face circuit i designed

[@HOLYISLANDAUDIO]

Do you mean you'd wanna add it into a pedal you already have? You'd want to wire it so the send is going directly to the input of your effect and the output of the effect is going directly to the return. Depending on the effect you're adding it to you may wanna use a different pot, might be worth auditioning a few, The pot I use in this video was just the value I'd had the best results with in most instances! 👍

[@princessfromaldershotuk9553]

Hi, great video! I've built this pedal, but it kills the signal of the connected effects when the footswitch is disengaged. Is there a way of adding a switch to keep the effects on when the Feedback Loop is off? Or have I done something stupidly wrong?? Thanks in advance!

[@HOLYISLANDAUDIO]

That’s what it’s supposed to do! There’s a bunch of diagrams online for a feedback loopers with toggles to flip it into just a regular looper

[@antoineleonardon2863]

Hi !! Amazing stuff, about to start building one as my first pedal project! Was just wondering if you had a drilling template by any chance, even without the design, or if you know easy ways of making one ! Thank you for the vid !

[@HOLYISLANDAUDIO]

Hey, I think I just eyeballed it tbh. If you wanted to make one I’d recommend downloading a build guide pdf for a random pedal in the same enclosure size from somewhere like pedalpcb. They usually have a drill guide in there so you can use that as the template and add your own holes/move the existing ones.

[@antoineleonardon2863]

Ok thank you !

[@cavanray5327]

You drill the enclosures after they are painted and screenprinted without any painters tape? How do you not scratch the finish?

[@HOLYISLANDAUDIO]

🤷‍♂️ it’s pretty easy? Just be careful I guess

[@cavanray5327]

@@HOLYISLANDAUDIO I would assume it must be doable since you aren't the first I've seen do it, but so many diy instructions say you should use painter tape, but not having to do it would be alot faster.

[@HOLYISLANDAUDIO]

@@cavanray5327 Whenever I’ve seen other people use masking tape it’s usually because they’re measuring out their holes and marking out measurements on the tape stops you having to draw directly on the enclosure. I include the drill template into my artwork so don’t need to measure anything

[@cavanray5327]

@@HOLYISLANDAUDIO I assumed it was also to protect the enclosure. I'm talking about the blue painters tape btw. I would love to have the drill holes marked on the template, I just want to avoid the shavings scratching the paint.

[@willowsparks4576]

could it work without a pedal in the loop? like if i patched the send a return together or if i just wired it without one? Cause ive been lnterested in a feedback mod i saw for a big muff and thought i could use it for a pedal until i found this

[@HOLYISLANDAUDIO]

nope because nothing would be fed back on itself. a feedback loop for a big muff would be feeding the muff back on itself.

[@asterlb1885]

does the signal pass through the pedals in the loop (just without feedback) when the pedal is bypassed, or does it bypass the pedals in the loop entirely?

[@HOLYISLANDAUDIO]

bypasses the loop entirely

[@masongantt2089]

How would i wire it without the dc power source? Not planning on using an led

[@HOLYISLANDAUDIO]

Hey man, if you’re not using an led just ignore the dc jack and that column on the switch completely! You’ll still need to connect the ground lugs on the jacks to the footswitch though 👍

[@masongantt2089]

@@HOLYISLANDAUDIO thank you so much!

[@alexandertouchdown8737]

What inks do you use for silkscreening? I use marabu marastar SR and I get mixed results, I also saw you used a soft squeegee, personal preference?

[@HOLYISLANDAUDIO]

I use One shot enamel paint, 120t screen and a hard squeegee. Not sure what I was using back when I made this video though!

[@liam-br9md]

do you think this is feasible to build into a guitar?

[@HOLYISLANDAUDIO]

you could do but it would be pointless without having pedals in the loop

[@norskr6583]

about the A500K is it linear? no idea what the difference is, just wanna be sure

[@HOLYISLANDAUDIO]

nope, it’s logarithmic. That’s what the ‘A’ prefix means, if it was linear it would be a B500k. Each pedal behaves differently with a feedback looper so I’d recommend trying bunch of values to see what works best with what you have in the loop.

[@norskr6583]

@@HOLYISLANDAUDIO thanks for the quick reply!

[@kellenhess7246]

does the pot absolutely have to be 500k?

[@HOLYISLANDAUDIO]

not essential but you’ll have a different sweep to the pot!

[@gutbucket6184]

Bro some of your videos have like 200 views even though they’re really cool and that always kinda confused me.

Thank you! it’s just the way youtube works unfortunately 🤷‍♂️
