Has anyone picked one of these up? I'd be interested in knowing how the TS circuit was stol... err modified for this design to work well with bass and 18V. I'm out of 9V jacks on my DC brick and would like to chop out the charge pump and run it directly off of 18V.

there is such a remarkable effect
Image
in fact it is a clone of a tube screamer with a few mods:
in this case replaced by a 4K7 resistor to 1K resistor(more gain)
capacitor 47n to 330n capacitor(more low)
Power supply filter looks like this
Image
but what makes the capacitor 3 and the capacitor 7?
with respect to a tube screamer circuit are unnecessary :shock:

from the scheme only need to take the power filter

I'm poor at speaking English,and so please take care of me.

Moonshine is nearly Landgraff DOD drive at 18V.
Drive is 500K-A.
Tone is 5K-B.
Proof changes clipping, 1N4148's symmetry or LED and 1N4002.
*LED and 1N4002, same polarity is connected to these.

I swear to dog, this thread is indistinguishable from a Monty Python sketch.
So the Moonshine is YATS. OK, no surprises there. But what's with the SuperBolt schematic? Seriously.

see posts above
I explained that this tube screamer with power supply filter from superbolt

its 100% tube screamer with gain mod and low frequency mod
2 way clipping toggle switch
1) symmetrical 1N4148(or 1N914)
2) 5mm red LED with 1N4001

but I still can not understand the destination of the capacitors 3 and 7

My Moonshine's serial is #1200, and it has only C3, not C7.
C3 is connected between bias(+9V) and GND.
R8 and R10 form the bias(+9V).
Perhaps C7 is connected between bias(+9V) and GND like C3.

And the clipping LED is 5mm Ultra-high brightness LED(RED).
