Suhr Buffer Signal Buffer / Isolated Splitter – Used

The Suhr Buffer is a compact signal buffer designed to preserve clarity and high-frequency response through longer cable runs and larger pedalboards.

Alongside its primary buffered output, it features a transformer-isolated secondary output with switchable 180° phase reversal, making it particularly useful for dual-amp rigs where ground-loop noise or phase issues can occur.

This pre-owned example is fully functional and ready for pedalboard, studio or live use.

Preserve Your Signal

Long cable runs and multiple pedals can load passive pickups and reduce clarity.

The Suhr Buffer uses a high 1MΩ input impedance and low 150Ω output impedance to help maintain signal integrity while driving longer cables and more complex pedalboards.

Isolated Dual Outputs

Two outputs are provided:

• Output – Main buffered signal

• ISO Output – Transformer-isolated secondary signal

The isolated output is particularly useful for splitting a guitar signal between two amplifiers while helping reduce ground-loop hum.

180° Phase Reverse

A dedicated phase switch reverses the isolated output by 180 degrees.

This allows two amplifiers to be brought back into phase when their signal paths would otherwise partially cancel each other.

Fair Deal Music Verdict

The Suhr Buffer is a simple but highly useful addition to a larger guitar rig.

Its combination of transparent buffering, transformer-isolated second output and 180° phase switching makes it useful for both preserving signal quality and running two amplifiers cleanly.

The compact enclosure and extremely low current draw also make it easy to integrate into almost any pedalboard.

Supplied without a power supply, this is a strong pre-owned option for players looking to improve signal integrity or build a more flexible dual-amp setup.
