"Utterly without redeeming social value" preset.  Crazy vibrato in phase-offset loops.

The Repeat switch latches feedback anywhere from the default runaway setting on down.

EXP PED increases modulation depth while decaying the loops (+ base pitch shifting).

Not for the squeamish, but can be tamed (lower Mod) for fast-syncing phased looping.
