The circuit will vary between a gritty treble boost and a full-range boost
depending on the drain bias voltage of Q1. Around 7V will give you
something like a RangeMaster. Lower values around 4.5-5V gives fatter
results. Tweak to your tastes.

Notes
Extra power filtering cap
The original circuit design doesn’t
include a power smoothing capacitor
between 9V and GND, but you can
include one if you’d like some extra
filtering. Anything from 22uf to 100uf.
This can be added to one of the sets of V
and G pads in your build, depending on
which wiring method you’re using.
If you have a side-mounted DC socket
and you’re using the V and G pads on the
footswitch daughterboard, add your
extra cap to the V and G pads on the top
edge of your main circuit board, + leg to
V pad. Check the positioning of the
board, pot and DC socket to see how it’ll
best fit within the space in the enclosure
(note: the EPic Boost board is shown as
example) >>>
If you have a top-mounted DC socket
and you’re using the V and G pads on the
the top edge of the main circuit board,
add your cap to the V and G pads on the
left side of the footswitch daugherboard,
+ leg to V pad. It should mount on the
underside of the PCB so it’ll sit next to
the body of the footswitch when
mounted. >>>
