A Pedalboard Tool Designed for the True Bypass Era
As pedalboards filled up with true bypass pedals, a common issue arose: loss of brightness and dynamics as the total cable length increases. The EarthQuaker Devices Buffer/Splitter addresses this need precisely with a buffer circuit inspired by their "buffer/preamp" approach: preserving the high end and providing a slight boost in the lows without altering your tonal identity.
Who Benefits from the Buffer/Splitter and in What Situations?
This Buffer/Splitter is aimed at guitarists and bassists who want consistent tone whether in rehearsal, on stage, or in the studio. It is especially useful if you use many true bypass pedals, if your pedalboard is far from the amp, or if you switch between several setups (clean, drive, ambient) and want to maintain the same level of clarity.
Regarding routing, it quickly becomes indispensable for modern setups: two amps in parallel, a wet/dry chain (one direct output, one output to effects), or simply a dedicated tuner output to take it off the main path. It's also an excellent starting point for a "pseudo stereo" rig (two amp inputs or two effects chains), while maintaining a clear attack and more stable response.

Questions frequently asked
Is a buffer useful with many pedalboards without buffers?
Thanks to its 1 MOhm input impedance, this buffer preserves the sensitivity of pickups, especially passive ones. Its 100 Ohm output impedance helps to reduce high-frequency loss associated with long cable chains.
What connectivity does the EarthQuaker Buffer/Splitter offer?
The input uses a 6.35 mm mono jack and the two outputs are also 6.35 mm mono jacks. This setup allows distribution of the buffered signal to two separate paths.
Can it power two amps or a wet/dry setup?
Two mono outputs are available from a single input. They allow sending the signal to two amps or to a wet/dry rig. One output can also be dedicated to a tuner.
What power supply is needed for this buffer?
The required power supply is 9 V DC with center negative, using a 2.1 mm plug, consuming 15 mA.
Does the buffer alter the guitar's sound?
With an extended cable chain, the circuit is designed to preserve attack and highs. A slight bass boost is also noted, without acting as an equalizer.
