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.

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.

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 except for the two 224 resistors highlighted in yellow.

These need to on the bottom side of the PCB. The “103” resistor highlighted in purple

should be a “223” or 22k resistor. This typo will be corrected after Rev1.0. Resistors are

not polarized and can be inserted in either direction. You should lay 1/8 watt resistors

flat on their sides. If your kit came with any ¼watt resistors, you should stand them on

end as shown in the finished pictures on pages 4 & 5.

Step 2: Add the diode. 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.

Step 3:Add the 8 pin and two 14 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. See page 27 for

instructions on how to orient and install the ICs.
