Nutty Fuzz: Planning a build

[cozycam]

I'm starting to plan a nutty fuzz build but I have a few questions. Only my second build so I'm overly cautious.

Is there a parts list anywhere that shows what I'd need? I know it's printed on the PCB itself but I'm hoping to order things ahead of time. I've searched all over the forums and found a few posts that help but no full list.

Also, I added an expression input hole to the drill template for the normal 5 hole 125Bs. I'm just concerned I have the placement wrong. Could someone more knowledgeable than I double check it please?

You rock. Thank you so much!

I made a Tayda drill template for the Nutty Fuzz. Really it's just the normal 5 knob template with an extra hole for the expression input. Figured I'd share it here if anyone struggles like I did:

Are these the right ICs?

555 timer

386n

I have one built, it almost works but there's a loud hissing sound the whole time. Not sure why.

Yes to both chips.

Post a thread in the troubleshooting forum with some clear pics, and we'll mostly likely be able to help you get it sorted

Thanks for the drill template. It works pretty good, but it's a tight fit to get the board in there. I had to finish the enclosure and then solder the pots once the whole thing was put together. There's definitely not taking it back apart once it's all in there.

I bought a cheap caliper from Harbor Freight and did my measurements with that. I absolutely love this circuit/pedal, but it's a bitch to tame. The oscillation is totally out of control. If you're not using an expression pedal/slider, you've lost all control. Even then, it's still an untamed beast.
