i've been looking over the other comments on the a135-2. several voices have made very
good arguments for band pass instead of low pass filters. however, the advantage of low
pass filters in this context is that when they're open, they're off, so to speak.

i think if i were planning to send a few drum sounds through the thing, i'd also be hoping
for bpf's. but i sometimes find myself mangling vocals, guitars, drum machines and even a
synth (!) at the same time, for which the a135-2 would be a godsend, but i'd want to have
the option of no filter effect.

and now i'll shut up and leave some bandwidth for somebody else. promise.
