im kinda in the same boat, not much volume and not much fuzz either. no subbed parts and double checked all wiring and solder joints

im using a probe, when i get to ic1 pin 5 is when it starts "also tried 3 different chips and get the same thing"

led was wired to the board not the switch

just for the hell of it i changed from a dpdt to a 3pdt stomp and now its fine

i went through the debug process, and finally found something! i had a solder bridge between my diode's but couldn't see it until i pulled out my magnifying glass. now a new problem started, when the gain is up all the way it sounds like a distorted tremolo pedal! very choppy helicopter like. i just cant win

OK so i built a sinking with no subbed parts and was testing it outwith no switch or enclosure, sounded good but as if was lacking a little gain,no big deal i was gonna experiment with some diff. diodes. anyway i  wired in the switch put it in a box and now all its doing is acting like a clean boost! no gain whatsoever. and the gain pot makes it louder when at zero than full on. double checked the wiring  looks all good. any ideas as to where i should be looking?

this one has me stumped, i recently finished my 2nd ego build "1st one was for a friend and it turned out awesome so now i want one" everything seemed fine "sound-wise" until i hooked up the led, after i wired up the led there is a noticeable drop in gain, anyone ever heard of this?

so i finally got some sound out of this thing after some minor trouble-shooting,and i found d3 was bad, but now im getting a signal through the pedal but it sounds almost over distorted and if i turn the gain up all the way it sounds like a fuzz pedal! the only thing that i noticed was that pin 7 of ic2 was less than 1 volt even after swapping out the chip.
any thoughts?

yeah that's what im afraid of, so far i have a signal up to one of the ic's but coming out its extremely distorted so im kinda at a loss here . good luck with yours though.

does anyone know about fixing a digitech xp100? i picked up a broken one and would like to try and get it working, any help would be greatly appreciated

this is only the 3rd pedal i've made but it is the first single sided board, so my first question is -do components go on the blank side? second- is there any obvious reason i am only getting a signal in bypass and nothing when effect is engaged?
