second amp suggestions

[Jonathan Yandel <jonathan_yandel@yahoo.com>]

Fellow loopers, I'd like some suggestions regarding expanding my looping rig to two (guitar) amps: one pre-loop and one post-loop, so I could process my loops whilst playing guitar over them--you know how it goes...anyway, currently I am using a Rivera 100 watt combo for my main guitar amp, sending the signal via the effects loop into my looping gear, and then taking that signal and sending it to a Roland 50 watt keyboard amp.  Which, as you may have guessed, sounds pretty weak, especially for live situations.  My question is this: would it be wise to match the power from my main amp (i.e., using another 100 watt tube amp), or is that unecessary, as my Rivera would already be amplifying the guitar signal in the frist place?  As you can tell, amps are my weak subject, and any help would be wonderful.

Thanks,

jonathan
