Itīs a scam
Itīs exactly same circuit as all other modern SS Fender, same gain, EQ, etc. , harsh, buzzy, *just* it has a diode strapped (grid to plate) 12AX7 instead of a couple Red Leds.
So no "real tube" there, at least itīs not a gain stage, it has no +B feed, nothing.
"Nobody" uses Fender Distortion channel, much preferring a good pedal ahead of it.
Meaning donīt waste time polishing a turd.
I strongly suspect it was a way for Fender to use the huge amount of unusable/microphonic/gassy/you-name-it defective 12AXy they must have stockpiled by now.
The ones I saw had the 12AX7 wrapped in shrink wrap, go figure.
Best part is that user manual boasts: "look inside other amplifiers (mainly Marshall Valvestate ), youīll see a couple Red Leds shining in rhythm with the Music, thatīs cheating, we have a real tube" .... REALLY?
As of "blackface looks", I remember one Kustom ampifier which came in 2 versions: a Tweed looking one, suggested for Blues, with fake Tweed Tolex and matching control panel graphics, and a Modern Metal one, flashy, robotic looking ... *Ļ*exact same circuit inside**
Funny thing is that Musicians argued about them in some of the Guitar Forums and found them very different , praising one and shooing the other according to personal preference
EDIT: the real clipper is 100k R36 in series with signal, and back to back diodes V1a and V1b clipping to ground.
You get about 2V peak there, not too different from 1.9V found with Red Leds.
Slightly more rounded than plain duiodes, but not a game changer by any means.
Itīs followed by the infamous mid killing buzzy "Contour" control , here called "body", should have been called "scoop" because thatīs what it does.
To hide buzzyness, they lobotomize Treble control, instead of the 250k pot Fender EQ requires, they use 50k R60 pot in series with fixed 220k R166 so 0>10 knob sweep now is really 0>2 ... very cheesy.
Again, leave as is and use a good pedal, the alternative being full dirty channel uprooting and building something better there ... clearly not worth it.
