Bypass works, effect doesnt?
« on: August 30, 2006, 11:11:50 PM »
Hi all,

I have a problem. Ive populated the circuit board and hooked it up to a DPDT like this:



When I plug the pedal in, and the effect is off its fine.

When I switch the pedal on, it cuts off the sound and the volume pot does nothing.

I figure this means that my jacks are hooked up correctly. Is it a problem with my circuit then?

Any ideas?

OK I forgot to put the tranny in  ::)

Im still having issues though. With the tranny in, it only gives me short, very loud, very distored, bursts of sound.

Any ideas?

Cool, Ive got the Tranny the right way.

Still got problems:

When I turn the pedal on, i can faintly hear my guitar if i strumm lightly, if it bash the strings however the pedal seems to kick in and it gives me this intermittant, extremely distorted, bass farting out type sound.

You have the classic misbiased transistor.

Here you go:

I am missing something here.

Going through the test list.

There is no "circuit board end of the black battery lead". Also what is C1, C2 etc?

Multi set on 20 DCV. Battery plugged in. Lead plugged in. These are the readings I got.
