[sdiy] Tape head collage (pretty much not synth DIY, sorry)

[Tim Parkhurst]

I'll say it again: This is the friendliest and most knowledgeable group
around. Also, don't worry about the "non-synth related" question. Even
though the vast majority of the traffic here is synth related, pretty much
any audio / electronics related question is fair game. We occasionally
venture off into topics ranging from the Hubble space telescope to circular
waveforms (note: they don't exist) to Nixie displays!

By the way, let everyone know if you come up with some neat collages / sound
files. It sounds like a ton of fun.

Cheers!
