running two amps at once

["Andy Morris" <apmorris59@hotmail.com>]

Greetings fellow loopers,
     I have a question for you which may have been addressed in the past. 
I 
tried searching the list archives for the answer to my question before 
bothering everyone but that turned out to be a waste of time. So here we 
go. 
I'm well aware that an a/b switch is necessary in order to drive two 
amplifiers at once. What I am curious about is whether it is possible for 
me 
to send the loop signal from my boomerang to a smaller 2x12 amp while at 
the 
same time using my 4x10 to drive my lead signal. My reason for doing this 
is 
to cut down on some of the increased gain/distorted signal caused by 
playing 
over top of a musical sample through the same amp. I'm sure many of you 
have 
noticed that once you have more than two or three layers the sound is 
affected to a significant degree. So even if my two amp idea is 
unworkable, 
if any one had any suggestions for me in improving my sound your ideas are 
welcome. Thanks, take care all.
