I never considered myself to be an ambient guy, but maybe I just don't know it.  There's a slapback sync delay here before 1 octave & 2 octave upward shifts.  Everything pre-pitch shifter is at a minimum.  Nearly everything post-shifter and in the feedback loop is maxed out.  It ends up as blooming, almost metallic slices of octave shimmers.

I had the expression pedal mapped 0-50 on the Pitch-Decay, for a subtle to medium effects.  Ramp up to 100 for more extreme and in-your-face effects.  My favorite technique of late is mapping the HotSwitch to change Pitch-Decay at 50 to the FRZ position (Pitch+Verb).  I guess that makes me at least an ambient wannabe.
