Product Information
Full details
The Old Blood Noise Endeavors AB/Y Switcher is designed for guitarists and multi-instrumentalists who need a reliable, passive signal routing solution to manage complex pedalboard setups. Its primary benefit is the ability to instantly toggle between two different amplifiers or signal paths, or combine them for a layered sound. A key caveat to note is that while the signal switching is entirely passive and will work without electricity, you must provide a 9V power supply if you wish to utilize the visual LED output indicators.

Extended Product Information
FAQs
Does this pedal require a battery?
No, this pedal does not contain an internal battery compartment. It is designed to be powered by an external 9V DC power supply for the LEDs.
Will my guitar signal be buffered?
No, the signal path is entirely passive. It will not buffer or color your signal.
Can I use this to switch between two guitars into one amp?
Yes, you can run the pedal in reverse. Connect your amplifier to the 'Y' jack and your two guitars to the 'A' and 'B' jacks to select between instruments.
Does it work with stereo signals?
No, the AB/Y Switcher is designed specifically for mono signal routing.
What happens if I don't plug in a power supply?
The pedal will still function perfectly as an A/B or Y switcher; the only difference is that the status LEDs will not illuminate.
Troubleshooting
LEDs are not lighting up
Ensure a standard 9V DC center-negative power adapter is securely connected to the power jack.
Signal drop when switching channels
Verify that your instrument cables are fully seated in the jacks and check for cable failure by swapping to a known-working cable.
Hum or buzz when using two amps
This is likely a ground loop issue. Consider using an external ground lift adapter or an isolated transformer box between the switcher and one of your amplifiers.
Pros and Cons
Pros
- Simple, intuitive 'plug-and-play' operation
- Sturdy, road-ready metal construction
- Passive signal path preserves original tone
- Clear visual feedback with bright LEDs
Cons
- Requires 9V power to use the LED indicators
- Lacks isolated outputs which may cause ground loops in some dual-amp setups
- Limited to mono signal routing only
Setup, Compatibility & Care
To set up the AB/Y Switcher, connect your instrument cable to the 'Y' jack. Run separate instrument cables from the 'A' and 'B' jacks to your respective amplifiers or effects chains.
Power Compatibility: The device operates as a passive switcher, but it requires a standard 9V DC center-negative power supply to illuminate the LEDs. If no power is connected, the switching functionality remains fully operational, but the visual indicators will not light up.
Care Instructions:
- Keep the jacks clean by wiping them with a dry cloth periodically.
- Ensure the enclosure remains free of liquid spills.
- When not in use, store the unit in a cool, dry place to prevent moisture buildup within the internal components.
