Thanks for posting this one (and great work!). I'm going down the rabbit hole on IC Big Muffs and since the Ultrastoner is in my top 5 pedals, I had to try this one.
One small catch - I had a slight issue with the Volume (and I kept thinking - why doesn't lug one connect to anything? Is this a typo?). I looked over on the pcb layouts site and their board has VOLUME Lug 1 to GROUND. Once I did that - it sizzles...in a good way.
Now it's easier to see, it should be 150pF.
ReplyDeleteI've ckecked schematic vs layout and the tone section looks good. Does the Shape pot and Toan pot affect the sound?
ReplyDeleteI spotted a small bug, 100k resistor connecting Volume 2/Output should have top leg moved up one collumn, from I 17 to H 17. I'll update the layout.
That's the ticket! I could hear the tone section working before, but it was just very quiet. I'd say it's verified now.
DeleteGreat! I'll tag it!

ReplyDeleteI don't find info about this fuzz. It's a ic big muff with the tone bypass switch and a mid pot?
ReplyDeleteYes, that's exactly what it is, IC Big Muff w. Ultrastoner tonestack and tone bypass.
DeleteThanks! Looks nice.

SUGGESTED NOTE: Volume 1 to Ground
