A few notes to start with...
This build is not for the beginner. Please do not attempt unless you know what
you’re doing. The high parts count will make troubleshooting very difficult.
The board has been designed so you can easily add a Boner Boost as the post
boost, as the original boost section hasn’t won many hearts. Boner is
recommended if you want to add some oomph without changing the tone too
much. The original is... weird.
Version 2.1 makes adding the Boner simple - no hacks required.
Post boost is not stand-alone - it will only be engaged when the distortion is
engaged.
This circuit is standard, Negative GND. Your power supply should be Tip Negative /
Sleeve Positive. That’s the same as your standard pedals (Boss etc), and you can
safely daisy-chain your supply to this pedal.
The board is designed so you can easily run the Distortion part of the circuit at 18V
by adding the optional charge pump circuitry. The Boost section will still run at 9V.
You can even add a small switch or headers + jumper clip to select between 9/18V.
Be very careful when soldering the diodes, LEDs and transistors. They’re very
sensitive to heat. You should use some kind of heat sink (crocodile clip or reverse
action tweezers) on each leg as you solder them. Keep exposure to heat to a
minimum (under 2 seconds). Sockets are recommended for the ICs.
The long leg (anode) of the electrolytic capacitors go into the square pads.
The cathode of the LEDs (short leg) and diodes (striped leg) go into the square pads.
Snap the small metal tag off the pots so they can be mounted flush in the box.

Part numbers shown in BLUE are for the original boost. Ignore these if building the Boner Boost version. See page 5.
Parts listed in green are for the optional charge pump. See page 6 for power options.
Leave the pots and switches until last. You won’t have access to much of the underside of the PCB once
they’re in place. When soldering these, a good tip is to only attach a single pin of each at first. That way you
can easily melt the joint and reposition the pot or switch to get it aligned with the others before attaching the
rest. They’re difficult to move once fully attached.
If your pots don’t have plastic covers you’ll have to leave plenty of space between the board and the pot body,
otherwise you’ll short out the circuit. Place some thick card beneath the pots while you solder them in. Once
you have your first pin connected, take it out and ensure you have a good clearance.
The labels on the connector pads on the main pcb and the daughterboard are:
DI - Distortion IN, DO, Distortion Out, BI - Boost In, BO - Boost Out. Not that you need to know that. just
connect them together.
Footswitches mount with the tags horizontal, as the blue line of SW2 shows above.
R28 and R28 can go on either side of the daughterboard.
IMPORTANT! If you’r building a v rsion with th original boost,
plac a jump r as shown in r d abov .

Now you just need to place four jumper wires as shown below.
Boner Boost
The Boner Boost mod utilises component
spaces that already exist for the original
boost along with a few jumpers.
Place parts as listed in the BOM below.
Remember Q1 needs to go in the opposite
way around to how it is shown on the PCB

NO CHARGE PUMP,
EVERYTHING 9V
Leave out all the charge
pump parts (listed in green
in the BOM).
Connect these two pads with
a jumper.
CHARGE PUMP,
DISTORTION 18V
Place all the charge pump
parts (listed in green in the
BOM).
Connect these two pads with
a jumper.
CHARGE PUMP,
DISTORTION 9V/18V
Place all the charge pump
parts (listed in green in the
BOM).
The 18 / V / 9 pads are
spaced at 0.1” (2.54mm), so
you have some neat options:
Use a SPDT slide switch with
that pitch and drop it straight
in there.
Use header pins and a
jumper clip. Place the
jumper across the top or
bottom two sets of pins to
choose the power.
Wire a SPDT toggle switch
offboard so you can select
the power outside of the box.
Middle pin of the switch to
the V pad.
Power
9V? 18V? Up to you. If you choose to add the optional charge pump that will only have a bearing on
the distortion circuit. The boost, whether original or Boner, stays at 9V.
Aw maaaan... sooo sexy!
Connect everything up...
Connect everything up but the LEDs. That includes the footswitches. Connect the main PCB
to the daughterboard. The pads align perfectly so you have nice straight wire runs.
Ensure your power supply is 9V Tip Negative, or connect up a battery for now. If connecting
a battery, solder long lengths of wire to the +V and GND pads on the PCB, then attach the
battery to the other end of these. This saves desolding stuff from the board, which is a pain.
JACK SOCKETS
DC SOCKET
GND
+V
GND
SIGNAL
Ignore the third tag -
you only need that if
wiring up for battery.
SIGNAL is ACK IN and ACK
OUT on the PCB. Each socket
has its own GND connection
conveniently placed.
Once the sockets are connected... Plug in. Go!
If it works, crack on and get it in the box. If not,
troubleshoot. Check you have everything in the
right place and reflow any poor joints.
First thing to check - have you put in the
appropriate power jumper..?
What about my LEDs?
Pre-drilled enclosures are supplied with 3mm holes for the LEDs, rather than
larger ones that require a mounting bezel. Why? Because you can hold the LED
securely in place with the PCB. When you come to box up your lovely new circuit,
get the pots in place first. Then the jacks. Now, slide your LEDs all the way into the
PCB (short leg to square pad) and bend the legs ever so slightly so they don’t fall
out. Alternatively put a little bluetac on there. Now locate your footswitches into
place and tighten.
When everything is secure, let your LEDs slide down into the holes - use some
needle-nosed pliers or skinny fingers to position them fully in the holes. I won’t kid
you, its a little fiddly but worth it for the neat finish you’ll get.
No bezel = happy pedal.
Once in place, solder.
Those little lights aren’t going anywhere!

This template is a rough guide only. You should ensure correct marking of your
enclosure before drilling. You use this template at your own risk.
Pedal Parts Ltd can accept no responsibility for incorrect drilling of enclosures.

It’s a good idea to drill the holes for the board-
mounted parts 1mm larger to give yourself some
wiggle room unless you’re a drill ninja.
