weird 808

[Mugshot]

first off, i am so not a tech, so obviously i cannot debug.

the thing is, i have here with me a DIY 808 clone, with the board layout taken from tonepad.com. my friend made that, and he pledged that he will replace the circuit board. but while there is no replacement board yet, i'd like to know what went wrong (just for curiousity, and im eager to learn DIY stuff as im a pedalhead  )

ok, here's the problem, and im sure some of you here have encountered the same thing before.
bypass is fine, no prob btw.
when engaged, none of the controls (level, tone, drive to a certain degree) seem to work as it should.

a) the volume knob doesnt cut volume even when zeroed in. sure it boosts volume to a certain degree, but i was expecting it to cut at least to a very minimal level when turned all the way down.

b) i get cloudy-thundery sounds when tone is either maxxed or zeroed. i had to set it midway to prevent this. and doesnt change the tone either way.

c) i cannot tell if the drive knob functions, but i think it does. but the defects of the tone knob and the level pot overshadows it functionaility (if it IS functional).

so there. im just curious to know what could've happened, since im planning to build one for my kid bro sometime.


thanks,

I think we would need more info. It sounds like a lot of things are wrong! Do you have any pictures of the "guts" of the pedal?
