Kit Instructions
Warranty:
BYOC, Inc. guarantees that your kit will be complete and that all parts and components
will arrive as described, functioning and free of defect. Soldering, clipping, cutting,
stripping, or using any of the components in any way voids this guarantee. BYOC, INC
guarantees that the instructions for your kit will be free of any majors errors that would
cause you to permanently damage any components in your kit, but does not guarantee
that the instructions will be free of typos or minor errors. BYOC, INC does not warranty
the completed pedal as a whole functioning unit, nor do we warranty any of the
individual parts once they have been used. If you have a component that is used, but feel
it was defective prior to you using it, we reserve the right to determine whether or not the
component was faulty upon arrival. Please direct all warranty issues to:
[email protected] This would include any missing parts issues.
Return:
BYOC, Inc. accepts returns and exchanges on all products for any reason, as long as they
are unused. We do not accept partial kit returns. Returns and exchanges are for the full
purchase price less the cost of shipping and/or any promotional pricing. Return shipping

Tech Support:
BYOC, Inc. makes no promises or guarantees that you will successfully complete your
kit in a satisfactory manor. Nor does BYOC, Inc. promise or guarantee that you will
receive any technical support. Purchasing a product from BYOC, Inc. does not entitle
you to any amount of technical support. BYOC, Inc. does not promise or guarantee that
any technical support you may receive will be able to resolve any or all issues you may
be experiencing.
That being said, we will do our best to help you as much as we can. Our philosophy at
BYOC is that we will help you only as much as you are willing to help yourself. We
have a wonderful and friendly DIY discussion forum with an entire section devoted to the
technical support and modifications of BYOC kits.
www.byocelectronics.com/board
When posting a tech support thread on the BYOC forum, please post it in the correct
lounge, and please title your thread appropriately. If everyone titles their threads
“HELP!” then it makes it impossible for the people who are helping you to keep track of
your progress. A very brief description of your specific problem will do. It will also
make it easier to see if someone else is having or has had the same problem as you. The
question you are about to ask may already be answered. Here is a list of things that you
should include in the body of your tech support thread:
1. A detailed explanation of what the problem is. (more than, “It doesn’t work, help”)
2. Pic of the topside of your PCB.
3. Pic of the underside of your PCB.
4. Pic that clearly shows your footswitch/jack wiring and the wires going to the PCB
5. A pic that clearly shows your wiring going from the PCB to the pots and any other
switches (only if your kit has non-PC mounted pots and switches)
6. Is bypass working?
7. Does the LED come on?
8. If you answered yes to 6 and 7, what does the pedal do when it is in the "on" position?
9. Battery or adapter (if battery, is it good? If adapter, what type?)
Also, please only post photos that are in focus.

This is what your kit should look like when it’s complete. Your kit may come with
different color capacitors, switches ect. Don’t be alarmed by this. They all still do
the exact same thing.

Populating the Circuit Board
Step 1: Add all the resistors. Resistors are not polarized and can be inserted
in either direction.

8
Step 2:Add the diodes. Be sure to match the end of the diode with the stripe
to the layout on the PCB. The 1N4148 diodes are highlighted in blue, and
will have a single black stripe. The 1N4001 diodes are highlighted in red and
will have a silver stripe. The striped end should go in the square solder pad.
Your Ge diodes may have a single stripe, two stripes, or a dot. The easiest
way to make sure your orientation is correct is to place the same side into the
square hole of all the Ge diodes. So if you have a single stripe, put that into
the square hole of all the Ge spots, if you have two stripes, pick a stripe and
put that one into the square hole for all the Ge diodes. In this configuration,
the Ge diodes are used for clipping. As long as they’re oriented as outlined
above, they will work.

9
Step 3: Add three 8 pin IC sockets. ONLY SOLDER THE SOCKET!
NOT THE ACTUAL IC! This is a socket. The sockets get soldered to the
PCB. The ICs get inserted into the sockets. The actual IC chip itself, never
gets soldered. You will insert the IC into the socket after the entire pedal
has been built.

10
Step 5:Add the film and ceramic disk capacitors. These are non-polarized
so they can go in either direction. The ceramic disc capacitors are
highlighted in yellow.

11
Step 6:Add the aluminum electrolytic capacitors. These ARE polarized,
meaning there is a positive and negative end. The positive side will have a
longer lead and goes in the square solder pad. The negative side will have a
shorter lead and a stripe running along the body of the cap, and goes in the
round solder pad.

12
Step 7:Add the battery snap. Be sure to place the red wire into the + eyelet,
and the black wire into the - eyelet. You want to thread them through the
strain relief holes first, as shown below.

13
Your build will look like this at this point. If it doesn’t, go back through the steps
and fix any issues.

14
Back of the PCB at this point.
Note the soldering, trimmed short to the PCB without stray leads or shorts. The
black markings you see on the PCB are from the flux from the solder. Flux usually
doesn’t negatively impact anything. You can clean it off with some rubbing alcohol
and a gentle brush if you’d like.

15
Step 9:Add wires to the IN, OUT, RING, -, +, (+), and the two Ground
êeyelets.Start by cutting four 2.5” pieces of wire and 4 pieces of 1.5”
wire. Strip 1/4” off each end and tin the ends. Tinning means to apply some
solder to the stripped ends of the wires. This keeps the strands from fraying
and primes the wire for soldering. Solder one end a 2.5” piece of wire to
each of the IN, OUT, and Ground eyelets on the PCB. Load the wires in
from the top and solder on the bottom of the PCB. Do the same with the
1.5” pieces of wire for the RING, -, +, and (+) eyelets.

16
Main PCB Assembly
Step 1: Mount the AC adapter jack to the enclosure. Your kit may come
with either an external thread or internal thread. Don’t get confused by this.
They still function exactly the same. You just thread the external nut on the
outside and the internal nut on the inside. The picture below is of an internal
nut jack.

17
Step 2: Flip the PCB over so that the bottom or solder side is up. Insert the
four potentiometers, toggle switch and the LED into the bottom side of the
PCB. DO NOT SOLDER ANYTHING YET!!!
The LED will have one lead that is longer than the other. THIS WILL GO
INTO THE SQUARE SOLDER HOLE.

18
Step 3: Hold the PCB in one hand so that the component side of the PCB is
in the palm of your hand and the bottom side with the pots, toggle switch
and LED is facing up. Now use your other hand to guide the predrilled
enclosure onto the PCB assembly so that the pots, toggle switch and LED all
go into their respective holes. Once the PCB assembly is in place, secure it
by screwing on the washers and nuts for the pots. Only tighten them with
your fingers. You do not want them very tight yet. Make sure you’ve
removed the nuts and washers from the pots and that you’ve also snapped
the tabs off the pots as well before installing.
Step 4: Turn the entire pedal over so that the component side of the PCB is
facing up. Lift the PCB up off the pots about 2mm just to make sure that the
back of the PCB does not short out against the pots. Make sure the PCB is
level and symmetrically seated inside the enclosure.
Step 5: Solder the pots, toggle switch and LED. You will be soldering on
the component side (top) of the PCB. After you have soldered them in
place, be sure to tighten up their nuts. TIP: only solder one lug of each
component at first. This will secure everything in place and still allow you
to wiggle things around if you need to adjust the fit of anything. Once you
have everything perfect, go ahead and solder everything else. Before you
solder, be sure to lift the PCB up away from the pots just a little bit. You
don’t want the PCB to short out against the B100k D.G. pot.

19
WIRING
Step 6: Connect the TIP (negative) terminal of the DC adapter jack to the
eyelet on the PCB labeled “-“. Connect the SLEEVE of the DC adapter jack
to the eyelet on the PCB labeled “+” farthest to the right. Connect the battery
disconnect terminal of the DC adapter jack to the second eyelet on the PCB
labeled “+” located in the middle of the other two eyelets .

20
Stereo (input) Jack
Mono (output) Jack
Step 1: Install the 1/4” jacks to the enclosure.
