While many guitarist swear by tubes there is a sizable group of solid state amplifiers. The Roland Jazz Chorus is a widely used solid state amp. The Line 6 DSP based amps also have a following. The blues giant Albert King used a solid state Acoutic brand amp with his Flying V guitar. Additionally, most bass guitar amps are solid state.
Guitar amps can have one or two channels. Typically the channels are not used together for stereo, but as two mono channels, one "clean" and the other "dirty". In live performances some guitarist use multiple amps in conjunction with stereo effects processors to achieve a stereo guitar sound. There are a very limited number amps that do this within a single chassis, the before mentioned Roland being one and I believe Gallien & Krueger made a few models.
I agree that music production is different in concept than music reproduction, but at one time Allan Holdsworth used VTL Tiny Triode for amplification. I'm actually a little surprised that tube high end manufacturers haven't branched out into instrument amp production in large numbers.
