Electro-Harmonix Big Muff Pi V4 (OpAmp)

I just fell in love with my larger (1590bb) OpAmp BMP but I really wanted a standard sized (1590b) pedal. I looked all over the place for a PCB transfer and attempted to make my own but this layout I found on FSB was perfect. Did not have to chafe much. I may look at doing a tone bypass switch on this also.

Here is the PCB in testing.

I hope to have this boxed up by this Sunday.
