This was a request. Appearantly a very powerful booster and eq circuit using inductors for sort of multiband wah sounds. The original ran on two 9v batteries for bipolar power operation but I included an onboard power inverter. Note that sizes of inductors varies a lot but hopefully there is enough room for them, especially the larger ones.

And a layout with more accessible 100mH inductors.
