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. The version of the kit we have is no longer offered by BYOC - they have changed this pedal, allowing only a single instrument input, and with it, they no longer offer a switchable phase-inversion option.

General Information
So the first generation of this pedal (the one we have) was a bit more "sloppy" than the current version. This can create some confusing behavior, but once you understand, it's still a very usable and interesting tool. The newer version is cleaned up a bit, but only allows for a single input - If you're looking to do anything stereo, in terms of your instrument or the
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
Input "A" is where it's at. Input A is switchable to one, the other, or both outputs. On this particular version from BYOC, there is also a phase inversion switch that both "Input A" and "Input B" have access to. There is a slight problem that may arise: If you have two instruments, with each plugged each into Input A and Input B respectively, then the instrument plugged into Input A will only be available through Output A, and the instrument plugged into Input B will only be available through Output B.
Any instrument plugged into Input "B" only goes to Output B only. In addition, if an instrument is plugged into Input B, the ability of Input A to send signal out through Output B is nullified.
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 |
---|---|---|---|
IC1b | TL072 | Does not Invert | Original |
IC1a | TL072 | Does not Invert | Original |
IC2a | TL072 | Does not Invert | Original |
IC3a | TL072 | Does not Invert | Original |
IC3b | TL072 | Does not Invert | Original |
From a "default" standpoint, this pedal, clearly, was designed not to invert phase while using it. In fact, a discussion from the BYOC forums essentially reveals as much...
Selectable Phase Inversion
Many participants on the BYOC board forums have looked at the Amp Selector/FX Router schematic and suggested an interesting option: Wouldn't be helpful to set up a switch that will toggle the signal inversion of the audio through one of the outputs?
Here are a few threads on the BYOC forums discussing the signal (phase) inversion switch:
- http://www.byocelectronics.com/board/viewtopic.php?f=52&t=44330
- http://www.byocelectronics.com/board/viewtopic.php?f=12&t=32756&hilit=amp+selector+phase
As this not only appears to be possible, but was designed into the pedal by BYOC, we will be implementing the signal phase inversion switch for our pedal as described in the forum.
If you opt to use this feature, here's how it goes:
Schematic ID | Electronic Part | Action | Phase State |
---|---|---|---|
IC2b (selectable) | TL072 | Switches | Depends on Phase Selection |
Here's how to use it:
If the Phase Inverter switch is set to: | |||
---|---|---|---|
Switch Toggle | Instrument(s) Plugged Into | Output Jack Used | Phase State |
"IN" | Input A | Output A | IN PHASE |
Output B | IN PHASE | ||
Input B | Output A | NOT AVAILABLE | |
Output B | IN PHASE | ||
Input A & Input B | Output A | IN PHASE | |
Output B | IN PHASE | ||
"OUT" | Input A | Output A | IN PHASE |
Output B | OUT OF PHASE | ||
Input B | Output A | NOT AVAILABLE | |
Output B | OUT OF PHASE | ||
Input A & Input B | Output A | IN PHASE | |
Output B | OUT OF PHASE |
The switch for selecting phase has nothing to do with whether you're selecting "Output A" or "Output B" for the function of using the separate outputs to switch between amplifiers.
