[Adam (synthDIY)]

These are all really interesting ideas..

This could be done with stepper motors on a sliding track, but you cannot increase the length of the metal in the spring, only how much which it is stretched. If you could adjust the transducers / contacts over time and "dampen" the unused portion of the spring, perhaps you could use a motorized "capo" and contact mic.

The Marshall Time Modulator is 90% there, but there is a difference between The Beatles "Lucy in the Sky with Diamonds" (tape) or Siouxsie & the Banshees "Dear Prudence" (tape, possibly with a Boss Jet Phaser) at 1:28 vs. Bauhaus "Terror Couple Kill Colonel" (Marshall Time Modulator)
