Martin Amps? Are you kidding?
Well, no. Martin had amplifiers in its product line up for the F-Series and the GT-Series. I have to be honest and say I don’t actually own any of these, but I keep coming across them in the course of the guitar research.
In 1962, Martin’s price list had two tube amps, two transistor amps, and three speaker cabs.
I’ll add information on these as and when I find them.
