Great suggestions thanks guys I'll check them out

Thanks for the reply, I'll check them out. I had a bad monkey when I was a teenager for a short while, didn't really know what it was capable of back then. Laughing about it now, preferred the grunge pedal and sold the bad monkey!

Hi all, Probably a stupid question as the title thread, but I would love some suggestions. I have a friend who has asked me to build him a drive pedal. He has only been playing for a year or so, and I let him use a slightly modified (switch for bright and bass response) TS9 based pedal. Anyway...

Turns out I'm a moron. I have to apologise to everyone for wasting their time, and I really appreciate everyones efforts. I generally use metal LED Bezels on my builds, the chrome ones. No drilling template with this one, but It's all good I'm a builder, I got this! Thought I'd be real efficient...

I dont know how to explain this, but if the pcb is in the enclosure with nothing tightened up but the foot switches and I push up on the pot shafts pushing them away from the enclosure the effect starts to work, as sson as I let go, it stops working. This happens with every pot, both green side...

I dont have a looper unfortunately, its definitely on the list. I have a reasonable feeling its the tone pot of the green channel. The effect cuts in and out a bit more so when it is wiggled than the others. Everytime I put it in the box it doesnt work, but will work evrytime out. Is it possible...

I'll have a look, gotta pull it out of the box again anyway, am I supposed to get more than just buzzing when I touch the audio probe to components?

yes, there has to be something going on though, should i probe it while its together, or pull it out again and see what i can see?

OK, Reflowed every solder joint to make sure they were good before I used the audio probe. Effect works outside of the box, doesnt work inside the box. Something must be grounding out or shorting right?

Cool, are they in the build docs for the circuit boards for the green side?

Will do

That looks pretty simple. So just follow the schematic (of which there isnt one on this build) and follow the signal till it stops and that is the problem area?

I'll check it out

whats that about the school canoe? I'd like to, but I don't have an audio probe, or really know what to do with one. Is it something I buy or something I make?

8.43V on the J201, presuming I have it in right being one of the SMD Fets. 8.43V again on pin 3 of the 2n3904

Yep, I was wrong, they measure good, man I am really struggling with this one. Was looking forward to it more than almost any other pedal ive built. Dont know whats wrong with me, got a trembling lune I just built before this one I have to trouble shoot too. I thought I nailed it as well, but it...

I'm in same postion really, blue side works great, but green side has no gain either, it makes noise but clean noise with a massive frop in gain. I noticed I have some resistors measuring different to what the bands say, I will probably to try rerplace them if the brainstrust says its worth it...

The resistors circled in red measured no where near what the coloured bands says on them, turns out my 15k resistors are rubbish. Would this affect the circuit to the extent I am seeing. Also only really checked what I thought was the green side.

Please bear with me, but I have begun to check all of the component values. Not only am I checking the bands but I have been putting a multimeter accross the resistors too. I have noticed that some resistors vary wildly from what is on the band. Eg the 1m down bottom left, can tell you its...

Same with the TL072s, I have sound but there is a big drop in gain when engaged, it turns a driven sound clean. I'll have a look at that resistor calculator, you think I have just put in wrong value resistor or cap?
