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 9: Populating The Circuit Board

    Populating the Circuit Board Step 1: Add all the resistors. Resistors are not polarized and can be inserted in either direction.
  • Page 10 Add the diode. Be sure to match the end of the diode with the stripe to Step 2: the layout on the PCB. The striped end should go in the square solder pad.
  • Page 11 Add the 16 pin and 4 pin IC sockets. ONLY SOLDER THE Step 3: 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.
  • Page 12 Step 4: Add the voltage regulator. Orient the 78L05 so that the flat side matches up with the flat side on the PCB layout.
  • Page 13 Step 5: Add the trimpot. This limits the amount of repeats. Most people what to set this so that the repeats eventually fade away after 10 seconds or so when the repeats knob is full turn clockwise. If you want infinite repeats, turn this trimpot up a little more. If you want self-oscillation (when the repeats runaway and keep getting louder) turn it up even more.
  • Page 14 Step 6: Add the film capacitors. These are non-polarized so it can go in either direction.
  • Page 15 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 16 By this time, your PCB should look like this.
  • Page 17 Step 7: Add the battery snap. Thread the solder ends of the battery snap into the strain relief holes from the bottom solder side 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.
  • Page 18 Step 8: 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. 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 19: 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 20 Step 2: Flip the PCB over so that the bottom or solder side is up. Insert the three B50k 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 21 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 and LED all go into their respective holes.
  • Page 22 Step 6: Connect the TIP (negative) terminal of the DC adaptor jack to the eyelet on the PCB labeled “-“. Connect the SLEEVE of the DC adaptor jack to the eyelet on the PCB labeled “+” farthest to the right. Connect the battery disconnect terminal of the DC adaptor jack to the second eyelet on the PCB labeled “+”...
  • Page 24: Wiring

    Wiring Stereo (input) Jack Mono (output) Jack Step 1: Install the 1/4” jacks to the enclosure.
  • Page 25 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 26 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 make a U shape & insert into lugs 3 &...
  • Page 27 Cut two 1” pieces of wire. Strip 1/8” off each end and tin. These will • be used to connect lugs/eyelets 1 & 7 Cut three 1.25” pieces of wire. Strip 1/8” off each end and tin. This • will be used to connect lugs/eyelets 2, 5, & 8 Step 4: Install the foot switch into the enclosure if it isn’t already.
  • Page 28 Step 5: Connect the pre stripped and tinned wires to the 1/4” jacks and connect the wires from the footswitch to the PCB. The wire from the IN eyelet goes to the tip of the stereo jack. The wire from the RING eyelet goes to the ring of the stereo jack.
  • Page 29: Installing The Ic/Finishing Up

    Installing IC/Finish up Don't forget to add the knobs, put the cover on the enclosure, and apply the bumpers to the cover.
  • Page 30: Operation Overview

    Operating Overview Repeats: Controls how long the echoes repeat or how quickly they fade away. Level: Controls how loud the echoes are. Delay time: Controls the time between echoes. Power supply: 9V battery or 2.1mm negative tip, between 9 and 18VDC Current Draw: 7.5mA Input Impedance: 470k ohms Output Impedance: 100k ohms...
