[sdiy] Moog guitar guts

[cheater cheater]

Ah yes, what ever moog music makes, it's gotta have a Moog LPF. Or six!

Just put them on rails and make em move. Mechanical knobs for the win,
I bet it's been a while since you've seen those in an electronic
instrument.
Then move 'em around and find the best position by experimenting.
As far as focusing the transducer rails: some very thin, very very
long coils would be required. imagine a pipe around which you wind a
coil (the wire going 'inside' it at every turn) and then make that
100x smaller.

As far as compression: definitely compression in feedback.
Would you say that the moog LPFs are used in the feedback in an
automatic pitch-tracking fashion with high resonance to clean up the
signal of any coil saturation artefacts?
The sound on the video did sound quite filtered/resonant.

Amos: drop the bs and just tell us the pat #s :) It's on the box anyways :)

Cheers
