CIRCUIT BOARD
Resistors (quarter-watt):
2x 10 ohm
1x 3.3k
1x 4.7k
1x 1m
I chose to include all the options on
this build. Some elements, such as the
footswitch, are completely optional, as
any footswitch can be replaced by a
toggle. I opted for the footswitch, with
no knowledge of the sound of the grit
increase, and if I had to do it again, I
would have opted for a toggle switch.
I will still include the instructions for
building the footswitch, but please note
that I recommend the toggle, as the
effect is marginal.

aside, we ask that readers be familiar with
a soldering iron and its accompanying
safety procedures before trying anything
listed here. Furthermore, if you fire the
amp up and it does not work, it will
need troubleshooting. Assuming the
components are not damaged, the pedal
will work. I built this very unit according
to these instructions and it worked so I
know the instructions are correct.
With that said, here’s what you need for
the board:
44
DIY //
CAPACITORS:
2x 47nF (film)
5x 100nF (film)
1x 47uF (electrolytic)
2x 220uF (electrolytic)
Potentiometers:
1x 1kB
1x 100kB
1x 10kA
SEMICONDUCTORS:
1x MPF102 transistor
1x LM386N IC
MISCELLANEOUS:
1x Veroboard (stripboard), cut and
drilled
1x 8-pin IC socket
(optional but recommended)
1x 3-pin SIP socket (optional but
recommended, for transistor)
Wire
Let’s build that circuit board!
NOTE: I built this slightly different
than my layout, to accommodate
a footswitch. This is not necessary,
or even recommended due to the
marginal gain of the sound.
