Hey all, so I am a thinking of cobbling together a single pcb with 3 different circuits on that will be switchable. Now my issue is the 9v power. If all three run through the same 9v power rail they will all pick up each others filtering etc. How do I best go about separating the 3 circuits on...

Not sure if this is the correct place to post this ! So I have had a go at putting a strip board together for the KAT plush treble booster. I was wondering if someone would be so kind to check it over ? A couple of things I do know: 1. It could probably be a bit smaller. 2. It could probably...

Hey all, so I am looking at a couple of different projects that require inductors. Now, some call for the L013 and some M013. I’ve had a look at the data sheet and I really don’t see any difference except he the size and price. Is anyone able to tell me what I am missing ?

After much need help for the mod and a very quick arrival from the USA to UK it’s complete. I think I was a little nuts squeezing it into a 1590b but it’s in there. Only thing iv had to do is file a bit of the back plate down to fit on. This was because of my poor choosing of position for the...

Can’t wait for the board to come, so knocked up a layout. I am going to attempt to put this is a 1590b, am I cutting it thin here ? Between the stomp and board is the best place I could figure for 3pdt toggle to do the Gilmour think. I am going to mount it on them little square alpha pots and...

A while ago @Chuck D. Bones provided a schematic of how to implement a switch and volume to the station wah for the Gilmour Seagull mod. Here is the thing, my dyslexic brain can’t get around schematics and I can’t visualize how to ‘actually’ implement it. Could anyone draw up a little diagram...

Hey all, I’ve built a few of these but I I have bumped into some issues with this one. There is normally plenty of dirt to be had. Basically the volume and gain is quite low. I have had a look at the other threads and tried replacing the 2N7000, same issue. I’ve worked through with an audio...

Hey all, I am looking for a matched quad set of JFETs. Does anyone have an idea of a uk supplier - I am struggling. I know I can get them from AION for around $9 but the shipping is like $18. I was considering buying 100 from banzai and a dca75 but that’s a lot of money.

Hey all, I hope some one can help. I’ve just built one of these having done a fair few before, without issue. On testing it sounds like a dying ZX Spectrum, or more accurately like it’s maybe not getting enough power. Hit a string and just glitches and disappears. The trim makes zero...

@Robert It would seem that ‘maybe’ this has been reverse engineered ??? Would love to see this fella.

Hey there Amigo’s, So I have splashed out on a SOT23 Peak tester, why not hey. I have 100 each of mmbf5457 and mmbfj201s. What bloody numbers am I looking for and what is an acceptable range for said numbers ? Thank you in advance all

Hey all, any recommended alternatives for the MPSA18 to go into the Abyss. I know they are not expensive but I have literally just placed an order with my supplier. I was thinking 549c ???

Hey all, recently built a flatline - super simple build !!! However, with any smudge of dirt it sounds like a helicopter i.e. it’s making this super quick pulsing sound. The more dirt, the worse it’s gets. Any thoughts ???

Hey there, is there likely to be a ‘Thanks Giving’ sale before I drop on a load of boards 😂

I’ve posted this in general but am not sure how to delete the post so I can put it here. Oh where do I start !!! I’ve build several of these without hiccup, really easy build - until this one. The pedal was exhibiting a super low volume and then nothing. I ran my probe and all was good until...

Oh where do I start !!! I’ve build several of these without hiccup, really easy build - until this one. The pedal was exhibiting a super low volume and then nothing. I ran my probe and all was good until till the output of Q3. I figured that it must of been a dud transistor. I cut the bugger off...

Hey all, just got a new batch of caps but all I could get are low ESR. Done some googling and searching on here but can’t get a definitive answer as to if they are actually ok in guitar pedals. What’s people’s take on them.

Hey all, how do you guys start trouble shooting a noisy pedal. I’ve worked out it’s not the PS as it does it with a battery. The noise is the same with any guitar with the volume up or down. When you play you can’t overly hear it but when not playing it’s like a sand storm. Holding the strings...

Hey all. Just built a super fuzz and on test, silence. Hit up the audio probe and there is nothing beyond the base of Q1. Thinking that Q1 may be buggered I pulled it and tacked on a socket (very crudely) and still the same, nothing on the collector. Anyone any thoughts as what the hell could be...

Hi all, I am in the process of implementing @Chuck D. Bones mods on the delegate but it’s not on a Pedal PCB board. I have managed to work most out working between the different schematics however I am struggling with the bias mod. Chuck has made it nice and simple with a pic when linking R6...
