I used to have that problem too. Now i just run my loops through a
cranked tube amp! Actually, i don't crank the amp much... just enough to
get it clipping a bit and fat-sounding. I depend on pedals for the heavy
grunge (a Prescription Electronics Germ (also my clean buffer), the fuzz
in a cheap Danelectro wah, and my beloved Rat). Oh, and everything gets
looped. I clean out my loops by manually turning feedback to zero, then
turn it back up to start looping again. I fade in and out by turning
knobs. Well, the Echotron loops, at least... the Vortex gets different
rules, as does the analog echo. 

The beauty of this setup is that my looped tone gets TONE, that whole
magnifying-glass effect of a hot tube amp and lots of gain. For years,
i've thought of distortion in the guitar chain as a sort of microscope,
magnifying tiny details. It leads me to making lots of small sounds,
just touches and squeals.  Plus, with the semi-hollow guitar, it feeds
back trivially, and much of my loopage is just layers of feedback at
different pitches. 

The disadvantage, at this point, is that everything gets looped whether
i want it to or not. Hopefully i'll make it more flexible later, without
losing the rich tone and touch-sensitivity.
