I finished my scrambler (tonepad layout) the other day, and it worked.  For some reason, today it doesnt work.   :x   Anyways...I'm debugging it with an audio probe, and I can get sound right after the input, but after C1 (10 nF=.01uF...right?) there is no sound.  I replaced the cap and double checked for cold joints, but no luck.  What else could possibly remedy this?

I was on such a roll too...my first 7 pedals worked like a charm.

Anybody?  Ive been debugging with a voltmeter and audio probe.  What is mentioned above is still happening.  I've checked RG's debugging page and the one on this site, and I'm still getting nothing.  Which bugs the hell out of me...cause it worked 2 days ago!  If anyone can help point me in the right direction, I would be in your debt.  P.S.  I'm out of beer, can someone help with that too?

Mahoney, if you get sound up to C-1 but not after that tells me your signal is going to ground, if you changed c-1 out and still no tone,?
is c-1 a polirized cap or just a plain coupling cap, if it's an electrolytic the + side of the cap needs to be faceing the input,, if it's got just a coupling cap you gotta have a bad tranny takin the signal to ground, or you have solder trace taking that signal to ground, post some voltge reading's from your tranny's on here, i'm sure someone will jump in here and help out.

Sounds like an intermitant short. Check your input and switch wiring for something loose. And check around your board for something bumping the enclosure and grounding.

So I checked the voltages on the transistors.  Hopefully I did it right though.  I connected the everything as if I was going to plug it into my amp for testing, then connected the negative lead of my DMM to ground, and the positive lead to the various pins...thats how it goes right?  Hopefully thats right, but here's what I got anyways:

Q1 (2N5306)  |E-8.70V|   |C-8.69V|  |B-8.68V|
Q2 (BC169B workalike from SB)  |E-.256V|  |C-3.19V|  |B-.888V|
Q3 (2N5306)  |E-3.27V|  |C-8.69V|  |B-4.29V|
Q4 (2N5306)  |E-3.27V|  |C-8.32V|  |B-4.29V|

I checked the pinout on the BC169B via a link in aron's faq, and it showed it as being the same as the 2N5306, hopefully that's correct.  Anways, there they are, any help is GREATLY appreciated.  Hopefully I did that right, if not, punch me in the face and let me know what I did wrong.  P.S. I'm still out of beer.  P.P.S.  Thank you all for your help.

This is the kind of stupid mistake I'd make:

Did you try a new battery?  Recently I reversed the wires on the stereo input jack so that the pedal drained battereies even when it wasn't plugged in.

It's easy to overlook the obvious (at least for me).

QuoteQ1 (2N5306) |E-8.70V| |C-8.69V| |B-8.68V|

Q1's not doing anything for you. The emitter, the collector, and base are all at the same voltage. I suspect a bad connection to ground on this one.

R.G. was correct as usual.  The emitter on q1 runs through a resistor then to ground, and I just swapped out the resistor, and it works like a charm.  It was either a cold joint or faulty part, but either way I'm as happy as a 2 peckered goat.  Thanks R.G.  (let me buy you something nice   )

Just don't buy him anything involving goats or metaphors....
