Bass Paralooper level pot? help a n00b

[Disco_Gee]

I've just finished testing my bass paralooper before i put it in an enclosure. It's based off moosapotamus' pcb, but i built on vero. It appears to work correctly - except for the level pot. I think I need to rewire it because if I bump it or move it a bit then I get no sound at all, but so long as the pot is in the right position everything works fine.

My question is, what exactly is the level pot supposed to do? Should it alter the overall output level of the pedal, or just the level of the wet channel? From the looks of Charlie's schem the pot should alter the overall level i think? It seems that mine is only altering the wet channel level. When i engage the effects loop, even with the level pot turned down to nothing, there is a huge boost in clean channel volume. I'm pretty new at all this (it's my first build) so I could very well have wired the pot incorrectly. I've used a 100k log pot. Looking from the top of the pot I've connected the left lug to ground, the middle lug to the output, and the right lug to vr1-3 on the CB. Any ideas?

Hmmm...

That's pretty hard to troubleshoot just from what you've said. It sounds like you've wired the pot OK, although there is more than one way to interpret "looking from the top of the pot."

As long as you have the output connected to the middle lug, the worst that would happen if you got the other two out of order is reverse operation - volume gets louder as you turn the knob counter-clockwise. From your description, could that be what's happening? The pedal would have a gain of 2 with the level control at max setting.

BTW, the level knob does affect the overall level, not just the effect level (the former is what the BLEND knob is for.) Hope this helps.

Ok, I've retested it. I think it is all wired the right way, the level pot is altering the overall level. When I touch certain parts of the circuit the level is double the normal level at the lowest setting, and about 10 times louder at the loudest setting. When I touch other parts of the circuit everything is fine - no sound at lowest level, about twice as loud at highest level. I think I have a grounding issue... I might try re-doing all the grounded wires.
