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
is the customer’s responsibility. This responsibility not only includes the cost of
shipping, but accountability of deliver as well. Please contact
[email protected] to receive a return authorization before mailing.
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.

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.

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 into the PCB
in either direction, meaning you don’t have to worry about orienting them.

Your kit will come with mostly 1/8 watt resistors. If you receive ¼watt resistors,
simply bend them so the body is vertical on the PCB. Below is an example

Step 2: Add the header sockets.

Step 3: Add the diodes. Be sure to match the end of the diode with the stripe
to the layout on the PCB. The striped end should go in the square solder pad.
The diode highlighted in red is the black body 1N4001. The diodes
highlighted in purple are the 1n5817 diodes. The diodes highlighted in
are the 1N914 or 1N4148 diodes. The diode highlighted in is the
4.3v Zener diode. This diode will look like a 4148, but will never say
‘4148’ on the body. The diodes highlighted in are the Germanium
diodes. If your Germanium diodes have two stripes, the white stripe will go
into the square hole.
