so i just came across this amp in my house, and i have no idea wtf it is lol. i opened up the back and it seems like its some sort of crossover between a tube and SS amp. pretty sure it was manufactuers in 1979-1980. if anyone know anything about this amp (if its tube, how much it costs, or anyhting) please reply to this thread.
I still have my old G100-212. They are a SS amp, one of the better ones. The preamp uses 4558 chips like a tubescreamer. Very nice cleans, takes pedals well, I still use mine as a keyboard monitor. However, they are not worth much.
