Brown Sound in a Box II (BSIAB2) |
Ed Guidry designed this one and I took his schematic from GeneralGuitarGadgets.com. The BSIAB 2 is apparently one of the most popular distortion circuits on Aron’s forum. tungngruv on diystompboxes.com kindly wrote to say that he built the circuit successfully with this layout.

As part of my High Gain Shoot out I plan this weekend- I built your layout of the BSIAB2. I plugged in and it sounded good, but WAAAAY too low end heavy. After comparing yours to GGGs layout I found that the 2 caps closest to the Vol pot are incorrect. You’ve got .022, GGG has them as .0022. I swapped them and the thing sounds great!

Thanks very much! I will fix that immediately!
That’s a great thread by the way. Thanks for starting that one.

I notice that you have D1 going to ground. The original schematic has it inline from 9v+ on to C4 and the R2/R6 1M resistor cluster. I’m also not seeing your C2 cap int he original schematic.
Did you add D1 and C2 for power filtering?
