From the post
I was struggling to get this one 21 columns wide max, so Miro will have to forgive me for the placing the Nature pot wires at different sides of the board. Sorry mate :o)
Info about the original:
The Model G captures the unique voice and response of an often overlooked brand of amps from the 50s/60s ~ the Gibsons that were right there at the beginning with Fender, Valco ,Vox and Marshall..
Somewhere near the tweeds and supros but with a stronger and clearer voice, and a particular upper mid sound and snarl.
The Model G is related to the Honey Bee the same way a Gibson Falcon or GA40 is related to a Supro … cousins with obvious similarities, but important differences.
The volume, drive and nature controls are on both models.
The C knob is a big part of the difference – it controls several things at once: the upper mids eq and snarl and slight speaker compression … like adjusting to different speaker choices and ages or even like moving a mic aimed at the speaker.
