I love this one.
I used 2n3903s instead of MPSA18. I biased like here:
I got rid of the complex ground scheme in the build doc, and wired the stomp switch PPCB style. The board fills a 1590bb2 and my input jack barely clears the PCB - the size did allow me to use the large knobs you see though, which I quite dig.
Highly recommended. I wish there was a 125B by PPCB though!
