What were Jerry's settings on the Phase 100 and is it possible to get Phase 100 sounds out of the Phase 90 or 45?
There's a picture of his 90's rack at Dozin ( http://dozin.com/jers/90srig/90s.html ) that shows the waveform rotary switch in the "8 o'clock" position - two big ovals with the line through them. I think that means deep sweep/wide frequency range. The speed pot was, I believe, wired out to a pedal.
Can't say about the 45/90. It would depend on how similar their factory waveform setting is to that of the P-100 I guess. I've read that the 90 has a deeper sweep than the 45 so that may be a place to start.
