Neat. Sounds like the Progressive Interference Cancellation my team patented
for CDMA years ago. Hear a signal, reconstruct it based on what you think you
heard, subtract the synthesized signal from the input, drop the noise floor.
Lather, rinse, repeat. (We got ~3x channel capacity from it in a CDMA context...)

Of course, it's a bit easier to reconstruct a CDMA signal than an analog
guitar signal, but we'll get there some day. I can't wait! ;)
