I started a pedal a few(?) years ago. Now I can't find the schematic and, after searching the internet, I can't even figure out what it is. Luckily, I covered the bottom of the pcb with liquid electrical tape stuff, so if there are identifying marks or words, I can't see them. :slap:

So, if anybody would know of a circuit with: TL071 and 4049ube
4 pots
2 stomp switches (one, I labeled "Tone")

and I called the thing "Tubish Fuzz", so that's probably a clue,

information would be greatly appreciated so I can trouble shoot the thing and get it running maybe. Thanks.

Yeah, that seems reasonable - but I can't find any mods with tl071 and 4049 and I copied the pcb from somewhere.

I'm leaning towards the Electro Harmonix Hot Tubes. Though it has 3 knobs and a tone toggle switch.
Controls are gain, tone and volume. What do your controls do?
It also uses a dual opamp and a 4049.

That's cool. I'll look at mods of Hot Tubes!

Thanks for the help. I solved the mystery by looking on an old hard drive I had at home. For what it's worth, the circuit is called "Slow Finger." It is by Stellan Lehrberg and is "a development of Mark Hammer's Tube Sound Fuzz Adapter." So it was down the Anderton tube sound fuzz line. Now, on to debugging.

Hello!

sorry for bringing this old thread back but I love the sound of a 4049 since I heard a red llama.

Could you share Slow Finger schematic?

Thank you so much!

I know it's a century too late, but this knowledge tends to dissappear:
