    Parts Checklist for BYOC A/B True Bypass Looper Kit Resistors: 3 - 4k7 (yellow/purple/black/brown/brown) Diodes: 3 - 5mm LEDs (Red, Yellow, and Clear Blue) Hardware: 1 - drilled enclosure w/ 4 screws 2 - 3PDT footswitch 3 - LED bezels 1 - AC adaptor jack 5 - ¼...

  • Page 5: Assembly

    Assembly Step 1: Insert the LEDs into their Bezels. You will need to push very hard. Use a pair of pliers to hold the legs of the LED while pushing. You will feel it snap into place. Do not try to use your fingers. You will only bend the LED leads.
  • Page 6 Step 2: Install the LED/Bezel assemblies in the enclosure. These will be a very tight fit, but trust us...you want them to be. Push the bezel into their respective holes through the top of the enclosure with your thumb. You will feel them snap into place. Orient the LED/Bezel assemblies so that the anodes are facing the jack side of the enclosure and the cathodes are facing the footswitch side of the enclosure.
  • Page 8 Step 4: Install the footswitches. Notice that the A/B footswitch is rotated a 1/4 turn. Below is the numbering system used to differentiate the solder lugs on a 3PDT footswitch.
  • Page 9 Step 5: Install the DC Adaptor Jack. Be sure to orient the jack so that the tip is facing up as seen in the pics.

  • Page 10: Wiring

    WIRING Step 1: Connect the cathode (- negative lead or shorter lead) of the Blue LED to LUG1 of the bypass footswitch. Connect the cathode of the Red LED to LUG3 of the A/B footswitch and the cathode of the Yellow LED to LUG1 of the A/B footswitch...
  • Page 11 Step 2: Clip the anodes (+ positive lead or longer lead) of the LEDs in half and bend the ends into small loops to make solder terminals. Note: Keep in mind that there will be bare metal left exposed on the LED connections that you will make in Step 3 that could potentially cause an electrical short if not done properly.
  • Page 12 Step 3: Connect the anode (+positive or longer lead) of the blue LED to the sleeve terminal of the DC adaptor jack with one of the 4.7k resistors. Trim excess component lead from the resistor. Connect one end of the remaining two 4.7k resistors to anodes of the yellow and red LEDs.
  • Page 13 Step 4: Connect the battery snap to the DC adaptor jack. The black wire connects to the tip. The red wire connects to the disconnect terminal of the sleeve. Connect the ring of the input jack to the tip of the DC adaptor jack. Since there will be two wires going into the tip of the DC adaptor jack, it's best to insert both wires and then solder at the same time.
  • Page 14 Step 5: Connect the Sleeve of the Input Jack to LUG 2 of the bypass footswitch. Connect the Sleeve of the Output Jack to LUG 2 of the A/B footswitch. NOTE: Wiring step 5 this way will leave on of the A/B status lights constantly lit, even when the looper is in bypass.
  • Page 15 Step 6: Connect the tip of the input jack to LUG4 of the bypass footswitch. Connect the tip of the output jack to LUG8 of the bypass footswitch. Jumper LUGS 3 & 6 of the bypass footswitch and LUGS 4 & 9 of the bypass footswitch. Since 2 connections will be made at LUG4, it's best to insert both wires and then solder at the same time.
  • Page 16 Step 7: Connect LUG7 of the bypass footswitch to LUG5 of the A/B footswitch. Connect LUG5 of the bypass footswitch to LUG8 of the A/B footswitch.
  • Page 17 Step 8: Connect the tip of the Send B jack to LUG9 of the A/B footswitch. Connect the tip of the Return B jack to LUG6 of the A/B footswitch. Connect the tip of the Send A jack to LUG7 of the A/B footswitch. Connect the tip of the Return A jack to LUG4 of the A/B footswitch.
  • Page 18 Step 9: Test your bypass looper. If everything works the way it's supposed to, use the cable tie to bundle your wiring. If it's not working correctly, trouble shoot your build and getting working properly before you tie the wiring.

  • Page 19: Operating Overview

    The BYOC A/B True Bypass Looper combines both features of an A/B box and a True Bypass Looper. It gives you the abilities of a bypass looper, but with two looping channels to choose from.

  • Page 22 Alternate wiring for Step 5: If you'd prefer that your A/B status lights be off when the pedal is in bypass, wire this way. Connect lug 2 of the A/B footswitch to lug 1 of the bypass footswitch. Do not connect lug 2 of the A/B footswitch to the sleeve of the out jack.
