Endorphin.es Golden Master Pedal

Multiband polish and loudness control for your pedalboard.

The Golden Master Pedal is the floor-friendly version of Endorphin.es’ acclaimed Golden Master Eurorack module—a three-band stereo audio processor built for stage use. Designed to live at the end of your signal chain, it offers compression, EQ, mid/side processing, and stereo enhancement across low, mid, and high bands—giving you powerful, studio-style mastering tools in a pedal format.

Each band features its own compressor, EQ, stereo enhancer, and mid/side processing, all internally run at 32-bit precision with 24-bit / 96kHz audio I/O. An intuitive control layout keeps things fast and tactile during performance: each band has a single dedicated knob for compression amount, while a global threshold adjusts overall dynamics across the spectrum.

Two footswitches allow you to bypass the effect or switch presets on the fly, while a dedicated expression input gives you hands-free control over master volume—ideal for dynamic control in live situations.
With pseudo-balanced outputs, the Golden Master Pedal can also serve as a DI box, delivering a hot, clean, stereo signal to front-of-house.
