BYOC Amp Selector FX Router. With this pedal, it's possible to route your instrument to more than one amp, or effects loop. It's even possible to output your instrument to more than one amp simultaneously. Ground lift transformers are available in the pedal as well to minimize ground loop hum than can occur when an instrument is plugged into more than one amp simultaneously.

Thermionic Studios has purchased this kit to build this pedal. We are in the process of building the pedal and will have more to report upon completion.

Controls

Image from expired Reverb.com auction
  • Switch 1 - "Transformer 1 Isolation Switch": toggles the ground lift function for Output A
  • Switch 2 - "Transformer 2 Isolation Switch": toggles the ground life function for Output B
  • Switch 3 - "Signal Inversion for Output A": toggles the phase inversion of the output for Output A
  • Footswitch 1 - "Both/One": Selects for either a single output, or both simultaneously
  • Footswitch 2 - "A/B": Selects between Output A or Output B

Bypass:True

The BYOC Amp Selector FX Router is True Bypass.

General Information

Switches

Footswitches:

  • The A/B footswitch selects/toggles between Output A and Output B
  • The BOTH footswitch turns on both Output A and Output B simultaneously.

Transformer isolation switches:

  • Switch A: This switch toggles the transformer for Output A on and off.
    • Switch flipped to the left is ON; flipped to the right is OFF.
  • Switch B: operates exactly the same as Switch A, but for Output B.

Operation

If you plug an instrument cable into:

  • Input A without anything plugged into Input B then the pedal will send signal to both Output A and Output B.
  • Input A while also having a cable plugged into Input B, then the pedal will only send signal to Output A.
  • Input B then the pedal will only send signal out to Output B

If you wish to use the Signal Inversion switch please consult table below in the Phase Inversion section.

Pedal Manual

As of this time, BYOC has not issued a separate manual on how to use the pedal. We believe the best references are either this wiki page, or the instruction manual (linked above in General Information) at Buildyourownclone.com which describes the architecture of, and how to build the pedal.

Phase Inversion: No/Selectable

Our review of the schematic draws us to conclude that the BYOC Amp Selector and Stereo FX Router does not invert the signal.

Schematic ID Electronic Part Action Phase State
IC1a TL072 Does not Invert Original
IC1b TL072 Does not Invert Original
IC2a TL072 Does not Invert Original
IC3a TL072 Does not Invert Original
IC3b TL072 Does not Invert Original

This will have to be born out by testing and observation.

However, many on the BYOC board forums have looked at the Amp Selector/FX Router and suggested an interesting option: If it wouldn't be helpful to set up a switch that will toggle the signal inversion of the audio through one of the outputs to allow a musician to select for it to be either in-phase, or out-of-phase.

Here are a few threads on the BYOC forums discussing the signal (phase) inversion switch:

As this not only appears to be possible, but was designed into the pedal by BYOC, we will be implementing the signal inversion switch for Output A for our pedal as described in the forum.

Here's how to use it:

Signal Inverter switch
Switch Indicator Instrument Access Output Phase State
OFF Input A Output A IN PHASE
Output B IN PHASE
Input B Output A NOT AVAILABLE
Output B IN PHASE
ON Input A Output A OUT OF PHASE
Output B IN PHASE
Input B Output A NOT AVAILABLE
Output B IN PHASE
