Product Information
Full details
The EarthQuaker Devices Buffer/Splitter is designed for musicians seeking to maintain pristine signal integrity, especially when using extensive pedalboards, multiple amplifiers, or complex routing setups. Its primary benefit is preserving your original tone across long cable runs or through numerous pedals, ensuring maximum clarity. A potential consideration is its specialized utility focus, meaning it doesn't add effects but rather enhances the signal path. Key features include a dual-output buffer, high input impedance, low output impedance, and a compact, hand-built design.

FAQs
Do I need a buffer if I'm only using a few pedals?
It depends on the length of your cable runs. If your total cable length from instrument to amp, including pedal patch cables, is less than 15-20 feet, you might not notice significant tone loss. However, for consistent clarity, especially with vintage-style pickups or passive electronics, a buffer is always beneficial.
What is the difference between this and a simple Y-splitter?
A simple Y-splitter passively splits the signal, which can still lead to signal degradation and tone loss. The EarthQuaker Devices Buffer/Splitter uses active buffering on each output, which amplifies and strengthens the signal, preventing tone suck and impedance issues.
Can I use this to send my signal to two different amps simultaneously?
Yes, this is one of its primary functions. You can connect one output to your main amp and the second output to a second amp for stereo effects, more tonal options, or increased stage volume.
What kind of power supply do I need?
You need a standard 9-volt DC power supply with a center-negative plug (2.1mm barrel). It requires at least 15 mA of current.
Will this pedal add any distortion or change my tone?
No, the Buffer/Splitter is designed to be transparent. It provides unity gain, meaning it shouldn't alter the volume or the inherent tone of your instrument. Its purpose is to preserve your signal, not to color it.
Can I use this for stereo effects?
Absolutely. You can send one output to your left stereo path and the other to your right stereo path, or use it to create parallel stereo effects chains.
Is it true bypass?
This pedal is buffered bypass. When the pedal is engaged, the signal is buffered. When bypassed, the signal goes through a buffer circuit to maintain signal integrity even when the pedal is not active, effectively acting as a buffer for your entire chain.
Troubleshooting
No sound output
Verify that the power supply is connected correctly and is providing 9V DC with the correct polarity. Ensure all instrument and amplifier cables are securely plugged into the correct jacks.
Weak or thin signal
Confirm that the pedal is powered on. Check that the cables are not damaged and are fully inserted. Ensure the buffer is functioning by testing with and without the pedal in the signal chain.
Hum or noise in the signal
Try a different power supply or isolate the pedal from other power-hungry devices. Ensure all connected equipment is properly grounded. Check your instrument and amplifier for noise issues.
Only one output is working
Test each output individually by connecting only one amplifier or device. Check the cable connected to the non-working output.
Pros and Cons
Pros
- Preserves original guitar tone and clarity over long signal chains.
- Enables flexible signal routing to multiple amps or recording interfaces.
- Compact design saves valuable pedalboard space.
- High-quality components ensure reliable performance.
- Low power consumption makes it easy to integrate into existing power setups.
Cons
- Does not add any tonal coloration or effects; purely a utility device.
- Requires a separate power supply (not included).
- Limited to two outputs, potentially requiring additional units for more complex splits.
Setup, Compatibility & Care
Setup
- Connect your instrument (guitar, bass, etc.) to the INPUT jack.
- Connect one or two amplifiers, effects pedals, or audio interfaces to the OUTPUT 1 and OUTPUT 2 jacks.
- Connect a standard 9-volt DC power supply (center-negative, 2.1mm plug) to the power jack. Ensure the power supply meets the 15 mA current requirement.
- Engage the pedal by connecting your signal chain.
Compatibility
- The Buffer/Splitter is compatible with all standard electric instruments (guitars, basses, keyboards, etc.) that output a line-level signal.
- It works seamlessly with other pedals, amplifiers, and audio interfaces.
- Requires a standard 9V DC center-negative power supply.
Care
- Keep the pedal away from moisture and extreme temperatures.
- Clean the exterior with a dry or slightly damp cloth only. Avoid harsh chemicals or solvents.
- Ensure all cable connections are secure to prevent signal issues.
