Title: No effect in effect mode
Post by: Deep Blue on June 10, 2004, 01:59:24 PM
I have a boutique 69 fuzz face I built.. and bypass works, and when I switch to effect mode, it sounds clean, like I'm playing through bypass.  I can slightly manipulate the signal (mostly volume) using the pots, but something is obviously wrong.

Where there is supposed to be a 10k trim pot, I just put a 5k resistor.  Would that explain it?  Would being able to adjust that trim pot make that big of a difference in the tone?

I'm using germanium trannies from small bear with transistor sockets.. Should I try getting rid of the sockets?  Audio probe doesn't help because I don't have any signal loss.

Good to see you back, deep blue...

Check all of your connections all over the place.  That sounds like a problem...

And yeah, you do want a trimpot in there, if you don't have a trimpot lyting around , just use a norrmal pot, although I can't see that as the source of your problem.

My connections?  Alright, I'll give my wiring another looksee.  I used sort of crummy wire, which might be a problem.

Thanks for the welcome, by the way.  I was getting sick of all these random pedal parts all over the place, so I finally went out and got myself another soldering iron so I can dig back into this jazz.  :)

Did you look at the transistor pin's voltage readings?
 Does it do the same thing withought battery conneccted?

I would, but I don't have access to a multimeter of any sort.

I'm using a DC jack instead of a battery...  And, actually, at the moment, I can't get it to work at all.  I'm sure it's just shorting in various places - I've got it half out of box, half in, so it's sort of a mess.  In any case, I'm gonna go ahead and rewire a bunch of it.
