that the instructions will be free of typos or minor errors. BYOC, LLC does n ot
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, bu t
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:
[e-mail] This would include any missing parts issues.
Return:
BYOC, LLC 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 t h e

BYOC, LLC makes no promises or guarantees that you will successfully complete your k it
in a satisfactory manner. Nor does BYOC, LLC promise or guarantee that you will
receive any technical support. Purchasing a product from BYOC, LLC does not entitle
you to any amount of technical support. BYOC, LLC does not promise or guarantee that

experie n cin g.
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 h a v e
a wonderful and friendly DIY discussion forum with an entire section devoted to t h e
technical support and modifications of BYOC kits.
www .bu il dyourown cl on e.com/boa rd
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 t h reads
"HELP!", then it makes it impossible for the people who are helping you to keep track of
your progress. A very brief discription of your specific problem will do. It will also ma k e
it easier to see if someone else is having or has had the same problem as you. T h e
qu esti on you are about to ask may already be answered. Here are a list of things that you
should include in the body of your tech support t h read:
1. A detailed explanation of what the problem is. (not just, "It does n ' t work, h el p " )
2. Pic of the top side 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 othe r
switches(only if your kit has non-PC mounted pots and switches )
6. Is bypass w o rki n g?
7. Does the LED come on ?
8. If you answer yes to 6 and 7, what does the pedal do when it is " on "?
9. Battery or adapter.(if battery, is it good? If adapter, what t yp e? )
Also, please only post pics that are in focus. You're only wasting both parties' time if you
post out of focus, low res pics from your cell phon e .

Populating the Circuit Board
Step 1: Add the resistors. Resistors are not polarized, so it
does not matter which en d goes in which solder pad.

!
7!
Step 2: Add the diodes. Be sure to match the stripe on the end of the diode with the
stripe on the PCB screenprint. The stripped e nd should go in the square solder pa d.

!
8!
Step 3: Add the IC Sockets. DO NOT SOLDER THE ACTUAL CHIPS!!!! You will
put the chips into the sockets in the "Installing the ICs" portion of the instructions. See
page 22 - 23 for more details. Each socket has a notch in one end. You should match
that notch up with the layout on the PCB and solder the socket directly to the PCB .

!
9!
Step 4: Add the film and ceramic disc capacitors. These are not polarized and can go in
any orientation. The caps highlighted in yellow are the ceramic disc capacitors.

!
10!
Step 5: Add the transistors. Be sure to match the flat side of the transistors with the flat
side on the PCB screenprint. The transistor highlighted in yellow is a 2N5088 or 2N5089.

!
11!
Step 6: Add the internal trimpots. These confuse many people because the trimpot itself only
has 3 legs, but the PCB has 5 holes. The PCB has 5 holes so that it ca n accomodate a
variety of different trimpot brands and models. There should only be on e way the trimpot
will fit into the PCB without having to bend the legs.
SEE PAGE 25 FOR INSTRUCTIONS ON SETTING
THE TRIMPOTS

!
12!
Step 7: Add the aluminum electrolytic capacitors. These are polarized. The po siti v e end
will have a longer lead and should go in the square solder pad. The negative end will have
a shorter lead with a black strip running down the body of the capacit or.

!
13!
Step 8: Add the battery snap. Thread the wire into the holes first, then into the eyelets.

Main PCB Assembly
Step 1: Flip the PCB over so that the bottom or solder side is up. Insert the three
potentiometers and the LED into the bottom side of the PCB. DO NOT SOLDER
anything yet!!!
The LED will have one longer lead. The longer lead goes in the square solder pad.
There will be two B50k potentiometers and one B1M p otentiometer. The B1M pot is
your delay time pot and should be mounted towards the top of the PCB . The other two
pots are for delay level and r epeats.

!
15!
Step 2: 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 and LED is facing up. Now use your
other hand to guide the predrilled enclosure onto the PCB assembly so that t h e pots 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 . O n l y tighten them with your fingers. You
do not want them very tight yet. Be sure to keep your hand on the PCB so that it does
not fall off the PC mounting posts of the pots.
Step 3: 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 4: Solder the pots, toggle switch and LEDs. 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.

16!
Step 5: Install the DC Jack into the enclosure. Orient it as shown below.

!
17!
Step 6: Install the footswitch and IN/OUT jacks.

!
18!
Step 6a: Prepare the Footswitch. Orient the footswitch so that the flat sides of the solder
lugs are like the diagram below.
NOTE: There are no actual number markings on the footswitch. There are two correct
ways you can orient the footswitch. They are both 180 degrees of each other. Either way
is fine. It does not matter as long as the flat sides of the solder lugs are running
horizontal, not vertical.

Step 6b: Make a jumper between lugs 3 & 6 from clippings from the resistors.
Simply use your needle nose pliers to make a U shape & insert into lugs 3 & 6, then
solder.
