I have oscillation with ICL7660SCPA.
Just 7660SCPAZ. Not SCPA but SCPAZ. No letters before digits. Bought it here, check the picture of the chip.

Ichabod_Crane wrote:And now a technical question. I see the charge pump, and also a 12v regulator, right? The PSU of this pedal can be 12v or 18v. I suppose the pedal receive 12v or 18v, adjust it at 12v and the charge pump turn into 24v. Is it correct?

It's declared verified. A guy built it, and he said it sounds great. Indeed, I would have some more opinions about it, and eventually issues or tricks.

Since i'm interested in building this and it'll be my first pedal, should i buy the UK-electronic or can i save some by buying all the parts myself?

I know about some oscillation problem and I'm a bit worried.
I even know about the 560pf cap, which can replace the 47pf, but maybe getting the sound muddy.
