Aaron,
I experimented quite a bit with the NFB on what used to be a Ceriatone BM HRM. I felt that the original circuit was way too gainy and fizzy. Admittedly, there were a lot of mods going into this amp, but one of the significants was the change of the NFB to #102 values (maybe slightly deviating - lost my notes, unfortunately). It sounds much better to my ears now, especially with single coils.

The Dumbleland sounds very nice, I can almost hear what is missing from the recording :)

Looks fantastic :D do you want it road testing over the next 3 weeks?

I'm touring Australia, however I'm using a 65 Super Reverb..........


I'd rather have the SSS and a 4x 12 :D

Hey Aaron,

This is awesome!

Did you ever post the schematic? I have a set of these transformers and I love to take a crack at this amp.

I got to play these amps this year, his SSS amps are really cool especially with Aaron's Strat which is something else. Great SRV like tones and well as getting clean Hendrix tones. I look forward to visiting Aaron again in the future and try his builds out.
Yours Sincerely
