Two amps are FUN! I like to use my Boss delay and go to my main amp and then use a smaller ss amp for the delayed sound placed a ways from the initial amp. Maybe I should put the main amp next to the monitor, facing me and the "delay amp" behind me lying flat on it's back. That'd give some ambient echo. Hummm...
Another fun trick is to to split the signal with a delay and then put a phase shifter on the delayed signal. That'll give you some psychedelic grooviness!
I have a Boss Dimension C pedal that I really ought to use in stereo.
