Hey! I have two bandmasters and a twin reverb. All 3 AB763. All the same, all serviced recapped etc.

The sizzle im talking about seems to be inherent in these amps. I hear it in my amps as well as most demos you hear. You dont hear it with two rock, dumble clones etc, but i hear it in all fenders. I love almost everything about these amps, but would really like to find a way to correct this.
Bandmaster, Bandmaster Reverb or one of each?
With regards to the sizzle, are you referring to the normal or the trem channel?
Bright on or off?

To sort this out effectively, the fundamentals have to be established.

I think a lot of that “ buzzy overdrive” is inherent to the layout, that and the steel chassis have a more in your face character that exaggerates the effect . Extra long grid wires also do not help , even if shielded . Later 70s fenders complicate matters by being a rats nest of lead dress issues and alternative bean counter approved components.
