Depending on the venue, I would use a Fender
Princeton 65 for mono, or a Behringer PMH880S mixer for stereo.
I also have these Gallien Krueger lunch box amps which are so small but
Gallien Krueger 250ML
In 2000, American Musical Supplies had a fantastic half price sale
on Fender SFX Satellite amps. The Satellite throws the sound sideways
and it comes back to you ears from behind. Very cool, but I only use it
at home because it is too heavy to gig out with.
