Just got this two modules and super happy with them. the BBD is full
of possibilities and unexpected things you can do with it that just a
standard delay wouldn't be able to do, it can create some really nasty
sounds or just color things slightly. A little confused about how all
the polarity switches affect things, so if anyone wants to shine in on
this please do.

Additionally, I got the a-126 moded so I can use the quadrature LFO to
drive it and it can create a whole new array of subtle sounds when
used this way, I recommend doing this to anyone that owns an a-126.

success!
