A CAUTIONARY TALE: I finally opened this up after more than a year and found that the center lug of the treble pot wasn't even soldered... Its easy to make stupid mistakes. Now the pedal works and sounds beautiful. Thanks @Feral Feline for your help!

Futzed around with it today but still nothing. Might just be the transistors I have. I don't have very good luck with Ge circuits! The attack knob kinda swells in and out at lower settings too.

Thanks for getting back. Reflowed the solder on the switch and pots. The treble pot is giving me subtle changes but nothing else still. Is there something else I could check from there?

Hello, My Maestro FZ-1 build is getting a high pitched whine when engaged. I swapped through a handful of different transistors and nothing seems to stop it. Any pointers or options? Thanks in advance.

Hello, The bass, treble and mid boost switch all are not working. Volume and gain work as intended but no tone controls at all. Any help? I can give you voltages and pictures upon request but is there anything I should check first?

Hello, Just finished up the Conquerer Fuzz and it sounds pretty good! BUT all of the tone controls (bass, treble and the switch) don't seem to do much of anything. I think i can trick myself into hearing subtle differences but its a REAL stretch. Is that normal or is there something I...

Remember I said i'm an idiot? I had the jumper at the wrong spot. IT WORKS! I can't thank you all enough for your help. Thank you very, very much!

Well damn, i added a jumper between those points but still nothing. the only red circle place I get 9v is the diode.

phew. but yeah, no continuity between c101 and 1/8 of ic100.

TRIM1 pin 3 and the positive side of c101 = 9.39 I have to get my idiot variable out of the way: the bottom left corner of the pcb was filed down to fit the enclosure. Only slightly and taking care not to get close to the visible trace. Could this be the culprit? I have to lay that on the table!

I bought the j201's from guitarpcb.com and the receipt says "guaranteed genuine." I can't thank you all enough for the help!

r18 is only reading .55 and 1.92v But there is continuity between R18 and 1&8 of IC100.

Ah, Ok. So even with the IC removed I'm still getting low voltages. I reflowed the solder for those sockets and cleaned around it with alcohol/qtip but still no change. Where to go from here?

Yes thats how I took the measurements - I listed them starting at 1 and going up numerically. Here are new ones i took with a different DMM - pretty similar results. Thanks again for trying to help! IC1 .78 .06 0 .69 0 .66 .66 9.38 IC2 8.32 .06 0 .70 1.52 1.84 2.14 9.38 IC3 .58 .3 .28 0 .28...

Do the above readings help at all? What can I do differently? Thank you for your help.

I’m gonnna have to read up on how to test the voltages and get back to you in a few days - it’s something I’ve been meaning to get in to anyhow. Thanks!

Hello, this is my first post. Probably my 5th pedalpcb build but my first that didn’t work! Finished a minnow but all I get is a bypassed signal. Blue led flashes for a second while plugging in but after that no leds. Anything glaring? Any troubleshooting tips? Thank you in advance for your help!
