I didn't think to mark the "amp type" knob before removing .
360 degree hex encoder , splined shaft, have I got this right

With my mark on one end of the shaft slot at 6 o'clock , (so could be 12
o/clock ) then A/AB control V at that contact is 5V. From the circuit 5V
probably relates to lack of negative FB so "class A",
Then going clockwise 000005555550050
Anunciators ,
at 6 o'clock , Boutique Cl then xlockwise
black 2x12
tweed 1x12
tweed 4x10
ac 15
15TB
ac30
30 TB
UK blues
UK 70s
uk 80s
uk 90s
uk modern
recto
US higain
Boutique OD

I've placed the knob so the block of 6x 5V cover Vox AC15 to UK 70s ,
right
or wrong?




The above list roughly approximates from clean to very dirty.
Probably best to try and find the point where US highgain and Boutique OD
turn into the relatively clean black and tweeds, should be a step change in
gain/ tone.

But you really need a guitar to hear this.
