I drew up a perfboard layout based on the PCB above. I didn't label all the parts but it follows the PCB so it shouldn't be hard to figure out.

Re: Pelota 2: PT2399 delay [documentation] [documentation]
I'm less sure about separating the regulator, maybe you can fit it in a corner of the main board. My reasoning for separating the power is threefold. One, it isolates it away from the other circuits to keep down possible interference. Two, it allows you to have a layout for a power board that can b...

Re: Amptweaker - Defizzerator [traced]
The frequencies on the schematic for Buzz and Crackle appear to be wrong. When calculated they come out as 7.23khz for Buzz (22nf) and 3.38khz for Crackle (47nf), not 4.2khz and 2.5khz. To match those numbers, Buzz would have to be 38nf, and Crackle would be 62nf.

Re: SolidGold FX 76 Fuzz....questionable workmanship?
If you want to keep it just use a round file to oblong the hole till it's in the right spot. Desolder the jack and reconnect using wires so it can be repositioned. That will relieve the stress on the side of the box and the board. Use an extra large thin spacer on the outside of the jack to cover th...
