fsh-1 quit...any ideas?

I know this pedal gives people lots of problems...thought I had it licked.  I've built 5 of them and they all worked great but this has happened twice now.  While trying to eliminate whine and ticking problems(.0047 cap across pins 5 and 6 of IC4 eliminates the whine...no ill effects, keep the output jack tip lug and wire as far away as you can from the board) I must have shorted something out...at least I solved the noise issues before it went to hell:)  Bypass works fine...when engaged there is a volume drop, it passes signal but it's in a high frequency range and there is no wah or sample and hold going on.  All voltages check out, i've replaced all IC's and diodes, checked my electrolytics...the only thing I haven't tested or replaced are the jfets...but I think if any of those died it would be completely dead.  Any ideas??  THANKS

could be one of the jfets. I had a similar problem, replaced them and now everything is fine again

Unfortunately the only fets I have are MPF102s.  As long as I get the pinouts right...they might work enough to at least let me know if that was the problem.  THANKS

you're welcome

It ended up being the 2n3906...figured it out after replacing the jfets with 2 mpf102's and a 2n5457.  The 102's and the 5457 work well AND they are the correct pinout for the GGG circuit board.
