1959 Gibson GA-45T Maestro


This amp is very similar to a GA-40 but with a different speaker configuration. You don't really need a GA-40 with this amp around though. It sounds great! It is loud and clear with good distortion when you turn the treble knob all the way up. These amps with 5879 preamp tubes are always quite enjoyable. The tremolo has a lot of variety. It can be very slow and warbly, or fast and choppy.
