Nice! Your own circuit design?

 

Yesn there's a thread somewhere. The charge pump circuit its a touch noisy if it's placed before overdrive and compression but I use it last. Might build a bigger one with space for larger smoothing capacitors!

Reverse polarity power socket?

 

Artwork error... I did change it.

I used a charge pump for the bias voltage on a 1176 compressor and was pretty nervous, as I'd heard that dreaded whine on an earlier project, but it's completely silent. I put 4.7uF surface mount MLCCs from the -ve output to ground on the back of the board under the chip, followed by 10 ohms and another pair of 4.7uFs. And decoupled directly between the power pins on the chip. good luck!
