Dating blackface fender amps
We’ll come back to this later in the “blackface chapter” below where we’ll demystify some of the hypes with the popular AA864.
The AA165 is very rare and its circuit and tone is quite similar to the AA864.
All models have a push-pull (class AB) dual 6L6GC power amp configuration.
Unfortunately the Bassman was one of the first amps that CBS laid their hands on after buying the company from Leo Fender.
A couple of things in the circuitry were immediately changed in 1965 when the AA165 and AB165 replaced the AA864.
