Thanks for the reply, is it possible to replace the tone controls with a simpler circuit, that replicates the sounds with all bass/mid/treble set in mid position? I guess I could build according to the schematic but replace pots with fixed resistors, but maybe there is a simpler circuit that...

Aha, thanks for the reply. I was guessing it was an acronym but I could not quite figure it out :)

Hello all, I would like to build a clone of the Krank Distortus Maximus pedal, but to keep things simple and cheap I want to build it without the bass-mid-treble eq part. I already have two eq pedals on my board so I think I can live without even more eq controls, I only want the distortion from...

I am not familiar with YATS, is there a schematic available for that?

Hello all, This might be an impossible question but I will give it a shot anyway :) I have the following components left over from previous builds: 2N5088 transistors TL072 op amp BAT46 diodes I want to build some kind of overdrive pedal. Does anyone know a suitable circuit? I know these...

On one of my builds the input jack was shorted internally, signal to ground.

I will finish this thread with a photo of the final result, with slightly neater wiring :)

I am happy to announce that the problem is solved and the pedal is now working flawlessly. It turns out one of the IC:s (TL072) must have been faulty, most likely broken by me fumbling them into the sockets. I replaced all 3 IC:s and now all is good. I want to thank everyone who offered help...

Its Lego. One transistor in each hole :)

Hello all, I thought I could share two pedals I built recently. They are not pretty but they work and sound good. Lovepedal COT and Mr Black Doomstick 2 I just looked at the schematics while soldering, next time I think I will plan more ahead :)

Yes it's the "top" pot. I have only tried with my guitar as input, but by turning that pot you can sometimes find a "sweet spot" where sound is transmitted to the output, and you can also find positions where it just crackles, and other positions where it goes "beep" My knowledge of circuits is...

I have tried it both inside the enclosure and outside of it, there is no real difference except its a bit more noisy outside of the box. Its one of the pots that has a strange behaviour, but looking at the schematic I don't understand how, it's just connected in series between two stages of the...

I think I have them correctly in the sockets, but Im also thinking one of them might have gotten damaged from being removed and inserted several times. I have ordered 3 new ones, just to rule out a broken IC

It's 400 degrees Celsius, but I don't know how accurate it is. My process is similar to yours but I think I am trying to do it quicker, maybe too quick. Im afraid I will destroy the components if I heat them too long. I do try to direct the solder to touch the pad instead of the leg, but it's...

Thanks for the encouragement, I will not give up of course but when I posted I was really tired of this thing.. It's like every time I try, it malfunctions in a different way, sometimes dead silent, sometimes loud crackling and once in a while the sound that killed the aliens in "Mars attacks"...

I don't know if anyone is reading this, but anyway, I have decided to give up on this pedal for now, I don't know how to fix it. One minute it works fine and then out of the blue it starts crackling, or whining or go completely silent. And operating the top left pot you can get all of the above...

I think I need to practice soldering more. I use too much solder sometimes I think, I get these "balls" of solder on the components side, like on the resistors in the photo. And sometimes there is no solder at all in the holes. I don't know if this inconsistency is the reason for my troubles?

This took a very strange turn. I re did all the cables, adding some length for a bit neater routing. Still not working, AM radio in full swing and flickering led in bypass mode. Then I played a bit with the UniCab turned off, and then turned it on again, and suddenly it's working. No led...

A small update, I measured the voltage on al IC pins and noticed that pin 4 on IC1 had +5 v, which seemed wrong since that's the ground pin. I removed the IC and put it back again and now pin 4 is at zero v. I think I had managed to bend pin 4 so it touched the neighbour pin somehow...

I haven't quite figured out which one is which of the + lugs, so I always connect the red wire to both. It has worked in all my other pedal builds, and the led on this one lights up when it should, so I don't think this is an issue. But I might be wrong of course, wouldn't be the first time :)...
