Re: fretless looping guitars

["Michael P. Hughes, PhD" <M.Hughes@surrey.ac.uk>]

To bring this all back to the looping domain (lest we be cursed with OT 
onthe subject line), to those (seemingly numerous) souls who do loop with
fretless instruments - just how difficult is it to remain in tune with
oneself when looping?  Don't theose chords jar against a lead line played
90% in tune?  Or does the ear compenssate?  Or like violin players, do you
use a wide vibrato to cover?

PS to the person who was exploring straight-5ths tuning; good luck.  Tried
it for a while (FCGDAE, starting a semitone about bass guitar E) but could
never get the stretches in...
