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, LLC 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, LLC 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:
sales@buildyourownclone.com 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 the
full purchase price less the cost of shipping and/or any promotional pricing. Return

Page 7: Populating The Circuit Board
Populating the Circuit Board STEP 1: Add the diodes. Be sure to match the end of the diode with the stripe to the layout on the PCB. The stripped end should go in the square solder pad. - Page 8 STEP 2: Add the resistors. Resistors are not polarized, so it does not matter which end goes in which solder pad. Take your time and be sure not to confuse similarly banded resistors such as the 470k with the 4k7 or the 220k with the 220 ohm. If you have difficulty reading the color bands, use a digital multimeter to test the value of each resistor.
- Page 9 Step 3: Add the film capacitor. These are not polarized and can be inserted into the PCB either way.
- Page 10 Step 4: Add the Transistors. Be sure to orient the transistosr so that the flat side of the tansistor body matches up with the flat side on the PCB layout. Make sure to insert the 2N3904 transistor into the Q2 space highlighted in yellow.
- Page 11 STEP 5: Add the aluminum electrolytic capacitors. These are polarized. The positive 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 or white stripe running down the body of the capacitor.
- Page 12 Step 6: Add the battery snap. Thread the solder ends of the battery snap into the strain relief holes from the bottom solderside of the PCB and out through the top. Insert the solder ends of the battery snap wires into the topside of their respective solder pads. Solder on the bottom side of the PCB.
- Page 13 Step 7: Add wires to the IN, OUT, RING, and two Ground eyelets. Start by cutting four 2.5” pieces of wire and one 1.5” piece of 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.

Page 14: Main Pcb Assembly
Main PCB Assembly Below is a picture of an “internal nut” DC adapter jack with nylon nut. Your kit may come with a jack that looks like this, or it may come with an “external nut” jack with metal nut. Both have the exact same termination and both function identically. Internal nut jacks mount to the enclosure from the outside and the nut goes on the inside. - Page 15 Step 2: Connect the TIP (negative) terminal of the DC adapter jack to the “-” eyelet on the PCB with 2 inches of hook up wire. Connect the SLEEVE of the DC adaptor jack to the “+” eyelet on the far right side of the PCB with 2 inches of hook up wire. Connect the battery disconnect terminal of the DC adaptor jack to the “+”...
- Page 16 Step 3: Flip the PCB over so that the bottom or solder side is up. Insert the B10k(TEXTURE), B50k(BLEND) potentiometers, 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.
- Page 17 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 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 and toggle switch.

Page 18: Wiring
Wiring Step 1: Install the 1/4” jacks to the enclosure. - Page 19 Step 2: Install 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.
- Page 20 Step 3: Connect the pre stripped and tinned wires to the 1/4” jacks. Step 4: Cut 4 x 3/4” pieces of wire. Strip 1/8” off each end. These will be used to connect lugs/eyelets 1, 2, 7, & 8 Cut 1 x 1” piece of wire. Strip 1/8” off each end. This will be used to connect lug/eyelet Cut 1 x 1.5”...
- Page 21 be used to connect lug/eyelet 4. The longer stripped end will be used to jumper lug 4 to 9. Cut 3 x 2” pieces of wire. Strip 1/4” off each end. These will be used to connect the tip and sleeve of the IN jack and the tip of the OUT jack to the PCB. Cut 1 x 1.5”...
