Problem? Solution.

Introducing the Buffer++: The ultimate utility pedal. Pristine buffering, plentiful I/O, and advanced signal control. Route anything, adapt on the fly, and preserve every nuance of your carefully dialed-in sound.

Buffer++

The Empress Buffer++ is built for musicians who want total control over their signal path and the freedom to experiment. Whether you’re toggling between inputs, switching amps, summing loops, or doing something no pedalboard was ever meant to do, the Buffer++ has your back.

It builds on our legacy of transparent, low-noise buffers while pushing far beyond simple tone preservation. Unlike rigid switchers or static ABY boxes, you can switch between guitar and synth, convert stereo rigs to mono, or dial in warm, vintage tones, all without touching a single cable. With 12 powerful routing modes, input metering, ground loop rejection, and variable input loading for tone shaping, the Buffer++ makes complex setups simple.

This pedal isn’t just about cleaning up your signal. It’s about unlocking the rig you’ve always wanted to build but didn’t know how. Stop compromising. Start building.
