Signal Blender Stereo

Old Blood Noise Endeavors teams up with 29 Pedals to bring you the Signal Blender Stereo — a high-headroom, phase-coherent, stereo parallel mixer designed to handle complex effect routing with ease.

More than just a stereo signal blender, this pedal is a versatile problem-solver. It can serve as a stereo parallel effects mixer, a 1-to-3 splitter, or a 3-to-1 combiner, making it an invaluable tool for creative routing on any pedalboard.

Each channel — Clean, Loop A, and Loop B — has its own level control and footswitch, allowing you to blend and engage them on the fly. Trails switches let time-based effects in the loops decay naturally after bypass, while individual phase-invert switches for each loop help eliminate phase cancellation issues.

The Signal Blender Stereo offers stereo TRS input/output (with mono TS compatibility) and an internal “MISO” switch for splitting a mono input into stereo outputs. True Bypass mode engages when all loops are disengaged, and soft-touch switching keeps operation quiet and smooth.

For modern setups, MIDI control is onboard, allowing remote toggling of loops and trails. Internally, the pedal runs at ±15V for massive headroom and clean signal handling, powered by a standard 9V DC supply.

If you’ve ever wanted total control over your signal flow — whether blending clean tones with effected ones, running parallel stereo chains, or splitting and recombining — the Signal Blender Stereo delivers with studio-grade precision and unmistakable OBNE flair.
