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.
REVISION NOTES: Rev1.0 is missing a trace. See Step 13 on how to fix this.

Study this for a few minutes before you begin. This is what your kit should look like when it’s complete. If you come to a step
that is confusing, come back to this picture and take a look. It may help. Your kit may come with different color capacitors,
switches, relays, etc. Don’t be alarmed by this. They all still do the exact same thing.

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

Step 2: Add the 4.3v zener diode. The striped end of the diode will go into the square hole.

Step 3: Add the IC sockets. The sockets will have one end that has a notch in it. Be sure to orient the sockets so
that the side with the notch matches up with the notch on the PCB layout. 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 at a later point in the
build process.

Step 4: Add the film capacitors. Film caps are not polarized and can go into the PCB in either direction.

Step 5: Add the relays. Orient them so that the line that is printed on the relay is pointed towards either the square solder pad or
towards the notch in the outline of the relay printed on the PCB layout. These do no need a socket. You will solder them directly to
the PCB.

Step 6: Add the transistors. Orient them so that the flat side of the transistor matches up with the layout printed on the PCB. The
transistors highlighted in yellow are BS170.

Step 7: 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.

IMPORTANT NOTE BEFORE PROCEEDING: It is important that you cut your wires to the lengths
specified. Obviously, you don’t want to end up with a wire that is too short. But with this build in
particular, you don’t want to use more wire than is necessary. This is because the excess wire can make the
final step more difficult.
Step 8: Add the DC adapter jack. Use two 2.5” (6,5cm) pieces of wire. Strip one eighth of an inch (3mm) off
each end. The super8 does not use battery power, so there’s no need to connect the battery terminal of the adapter
jack.
see wiring diagram on the next page

Flip the PCB over and insert the wires into the back of the PCB. Solder on the top side. Connect the tip of the DC
JACK to the “-“ (negative) eyelet. Connect the sleeve to the “+” (positive) eyelet.

Step 9: Add the enclosed panel mounted jacks.
sleeve
tip
Ring

In this diagram, the sleeves are shown being connected by a black wire and the tips are shown being connected by a purple wire. This is only for
illustrative purposes. Your kit will only come with one color. These are stereo jacks, but we do not need the ring terminal, so nothing will be connected
there. Use 4.5” (11,5cm) of wire to connect the tip of the buffered input jack to the “BIN” eyelet on the PCB. Keep in mind that you will be inserting the
striped end of the wire into the back of the PCB and soldering on the top. The labels for the eyelets are located on the top side of the PCB. Use 3.5”
(9cm) to connect the sleeve of the buffered input jack to its ground eyelet shown by the ! symbol. Use 3.5” (9cm) of wire to connect the sleeves of all
the rest of the SEND jacks to there respective ground eyelets. Use 3.5” (9cm) of wire to connect the tips to there respective “S” eyelet. “S” is for SEND.
The tip of the SEND 1 jack will go to the “S1” eyelet. The tip of the SEND 2 jack will go to the “S2” eyelet…and so on.

Step 10: Add the PC mounted jacks. These go on the top side of the PCB. These jacks probably come with 3 plastic washers
(depending upon the brand). There is one beveled washer that goes on the outside. There are 2 flat washers/spacers that go on the
inside. You will only need to use 1 of these flat washers/spacers per jack. Be sure to remove the extras if your kit comes with them.
TIP: It may be helpful to only solder 1 pin on each of the PC mounted jacks just to hold them in place. Then insert the assembly into
the enclosure to insure that you have a good fit before soldering all 6 pins on each jack.

Step 11: Connect the foot switches to the bottom side of the PCB as shown in the diagram below. Use 2.5”
(6,5cm) wire to connect foot switch BP and 2. Use 3” (7,75cm) wire to connect foot switch 4 and 6. Use 4”
(10,25cm) wire to connect foot switch 8.
NOTE: When you install the footswitches into the enclosure, be sure to orient them as shown in the diagram
below, i.e., the solder lugs of BP and 8 should be pointing away from the inner walls of the enclosure and the
solder lugs of 2 and 4 should be pointing away from the 3 yellow “bank” LEDs (you haven’t install the LEDs yet).
