Has anyone tried setting a JamMan delay to single repeat (ie FB=1), taken
one of the outputs and fed it back through a volume pedal and mixer into
the input?  It would be one way of getting control over feedback, with the
only problem being the difficulty in matching the i/p and o/p to make sure
the loop doesn't either get louder or quieter ehen the pedal's on bypass.
If that were to work it would allow fading and replacing; added to the
delay-based looping advantages previously discussed, it would give more
functionality than regular JM looping, except for the use of multiple
