the exp pedal input. does it control the feedback level?
Fatback - do you remember what your settings were for these clips? I especially liked the first two.
Jack - I'm not sure of the exact settings but this will get you in the ballpark:
delay - 3-4:00
echo - 1:00
excess - noon (for the second part I dimed it.)
