ROLAND: BeeBaa AF-100

I've posted layouts for a stripped-back version of the Roland BeeBaa, but never for the full BeeBaa.  So here it is.

The Roland BeeBaa has a couple of extra options, not generally found on fuzzes of the era, mainly the treble boost and tone control.  The switching swaps between a treble boost and a fuzz with two tone settings (notch filter or direct).  The fuzz feeds into a tone control, bypassing the treble boost.

I've listed 2N3904 for transistors, but you can use just about any silicon NPN -  for my ears, lower gain transistors sound better, but you might like something higher.   

MLCC capacitors have been used for 1uf and 10uf caps to save on space. 

Bi-colour LEDs have been included to keep track of the switching.  You could use single-colour LEDs using the standard method or no LEDs if you prefer (not recommended due to all the switching options).

Drop the last 4.7n cap on the right if you want more sizzle in the fuzz.
