If your still working on this issue I have solved my really low output issues. The lone king I put electrolytic capacitors in the PCB instead of tantalums and I'm pretty sure I put in 22uf instead of 220nf which stifled the output. On the other pedal I put a 470nf instead of the 470pf it was...

Now it doesnt work outside the enclosure. I get a small amount of signal coming through and a whirring in the background like a plane engine is warming up. Assuming thats the charge pump. WTF.

PCB is kinda jammed in against the screw posts of the enclosure, could this distort PCB or effect things?

I'm pretty sure it's not the switch, it was actually finally 100% working before it went in the enclosure. I don't like how it fits in the enclosure im thinking about drilling a new one and seeing how it goes. Don't like the jack locations or PCB fit

Yep, as soon as it was in the box, it started squealing again. If the edge of the pcb is touching the inside of the enclosure in any way can that cause this? Spewing too, it worked fine out of the enclosure last night

Ok, thanks. Should hopefully be good to go.

For anyone who happens to look at this thread, I have replace c4 and have managed to trace the signal all the way through to the end and I believe the effect works. We'll see what happens when I box it up again. On another note, Jwin615, the audio was not on the points on the opamp that you...

Thanks for the response guys, much appreciated. I can read schematics and have a basic understanding of what the circuits are doing, but I wouldn't know exactly what to change in a circuit if I wanted to modify the sound if I didnt like it. Thats about my level but I am trying to learn more and...

So I have a few pedals to trouble shoot... I'm new to audio probing, but I'm learning. If anyone can give me some tips that would be awesome, any knowledge and experience is welcome. Just wondering, sometimes the signal is weaker on one side of a resistor to another, is that just due to the...

I got as far as the gain pot with audible signal when audio probing. there was signal on pin 1 of the gain pot and nothing on the other two pins really, had to do it quietly though as everyone is asleep here. From there nothing on c4 etc.

Hi Andrew, when you say ensure continuity of the gain and volume jacks to ground pin #1, do you mean ensure there is continuity between pin 1 and 3 of volume and gain pots? When audio probing I only really get a strong signal on the left lug of the pot looking at it from the back, or non shaft...

Yep, tantalums fixed it, pedal sounds great! Can't believe I did that, what an idiot. Thank you all so much for your help, only 2 pedals left to trouble shoot. You guys are great, sorry for wasting your time.

Yep will do. Sometimes I can get sound through it and sometimes I can't even audio probe it, this one has me puzzled.

Unfortunately, the problem persists regardless of whether there is a charge pump or not in there and remains the same not matter what type. I think I have to rule that out. That is some great info there that I will investigate, ground loops always seem like a mystery to me, thank you very much...

Thank you.

Yeah just looked at the build docs again, not sure how i went so wrong, 220nF tantalums, thanks for the heads up, very embarrassing. May as well order some and try that out, pretty sure it has to fix it.

Crap, I din't realise there had been more posts on this thread. In the meantime I have ordered more 220uf electrolytics and replaced them with no positive effect. Is that because I'm using electrolytics? There is some volume and the effect sounds like it should but unity is at full volume and...

just an update if anyone is interested, been re-flowing all solder joints. It went back to just noise for a while, now i have some sound through it and effect as well. not a clear as before but I can hear something. Will audio probe when I can get the opportunity to set it up. The loose...

Does anyone know what the potentiometer labels are for the Souldrive PCB, there aren't any build Docs?

As in one of the wire connections?
