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:
sales@buildyourownclone.com 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

  • Page 7: Populating The Circuit Board

    Populating the Circuit Board Step 1: Add all of the resistors. Note: The 120 Ohm and 10k resistors have the same color bands, just reversed. Find the 120 Ohm resistor with your multimeter before soldering any 10k resistors. One of the brown bands is the tolerance band, and will be slightly offset on the 120 Ohm relative to the 10k resistors.
  • Page 8 Add the diodes. Be sure to match the end of the diode with the stripe Step 2: to the layout on the PCB. The striped end should go in the square solder pad. The green diode is the 4001, the yellow diodes are the Germanium, and the red diodes are the 4148.
  • Page 9 Step 3: Add the 8 pin 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.
  • Page 10 Step 4: Add the transistors. Be sure to match the flat side of the transistor with the flat side of the transistor on PCB layout. The red transistors are 3904, the yellow transistor is 3906, and the green transistor is 5457.
  • Page 11 Step 6: Add the film (red outline) and the ceramic disc (yellow outline) capacitors. These are non-polarized so they can go in either direction.
  • Page 12 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.
  • Page 13 Step 8: Add the battery snap. Thread the leads into the strain relief holes first through the bottom side of the PCB. Then insert the leads into their respective solder pad hole on the top side of the PCB. The red lead goes in the + hole and the black lead goes in the – hole.
  • Page 14 Step 9: Add wires to the IN, OUT, RING, -, +, (+), and the one Ground eyelet. Start ê by cutting three 2.5” pieces of wire and 4 pieces of 1.5” 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 15: Main Pcb Assembly

    Main PCB Assembly Step 1: Mount the AC adapter jack to the enclosure. Your kit may come with either an external thread or internal thread. Don’t get confused by this. They still function exactly the same. You just thread the external nut on the outside and the internal nut on the inside.
  • Page 16 Step 2: Flip the PCB over so that the bottom or solder side is up. Insert the five 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. THIS WILL GO INTO THE SQUARE SOLDER HOLE.
  • Page 17 Step 3: 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, 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, toggle switch and LED all go into their respective holes.

    WIRING Step 6: Connect the TIP (negative) terminal of the DC adapter jack to the eyelet on the PCB labeled “-“. Connect the SLEEVE of the DC adapter jack to the eyelet on the PCB labeled “+” farthest to the right. Connect the battery disconnect terminal of the DC adapter jack to the second eyelet on the PCB labeled “+”...
  • Page 19 Stereo (input) Jack Mono (output) Jack Step 1: Install the 1/4” jacks to the enclosure.
  • Page 20 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 21 FOOT SWITCH SOLDER LUG DESIGNATIONS Step 3: Wiring the foot switch. Make a jumper between lugs 3 & 6 from clippings from the resistors. • Simply use your needle nose pliers to bend a piece of clipping into a U shape &...
  • Page 22 Cut a two 2” piece of wire. Strip 1/8” off each end and tin. • Strip ¾” off the other end and very carefully tin. You do not want too • much solder on this end. Thread the longer stripped end into LUG4 and through to LUG9. •...
  • Page 23 Step 5: Connect the wires at the top end of the PCB to the IN and OUT jacks. The “out” eyelet will go to the tip of the OUT jack and the “in” eyelet will go to the tip of the IN jack (refer to page 22). Connect the ground eyelet on the left to the sleeve of the IN jack and the ground eyelet on the right to the sleeve of the OUT jack.
  • Page 24 Installing IC/Finish up Don't forget to add the knobs, put the cover on the enclosure, and apply the bumpers to the cover. The red areas indicate pin 1 of the M5218L IC, and the location of those pins on the PCB. Remember that you are not soldering the IC directly to the board, you will use the provided sockets.
