Old Blood Noise Endeavors Signal Blender Stereo Basic Parallel Effects Router

The Signal Blender Stereo, crafted in collaboration with 29 Pedals, is the ultimate tool for musicians seeking versatile parallel signal chains. Building on the acclaimed 2019 original, this updated version offers enhanced signal headroom, improved phase response, and full stereo functionality, making it a must-have for complex rig setups and creative sound design.

Designed to seamlessly split or combine signals, the Signal Blender Stereo provides two stereo effect loops alongside the clean signal path, enabling flexible parallel routing. Whether blending effects or managing multiple outputs, its intuitive controls and rugged build ensure professional performance in any studio or live environment.

• Mono-to-stereo splitting option via internal dipswitch
• Individual volume controls and footswitches for Loop A, Loop B, and clean signal
• Trails switching for delayed signal cut-off on both loops
• MIDI control for on/off and trails switching
• Phase invert toggles for both effect returns
• True bypass option when all loops are off
• Top-mounted jacks for convenience and soft-touch switching
• Hand-made in Oklahoma, USA
• Powered by optional 9 V DC PSU (centre negative, 2.1 mm, ~500 mA current draw, not included), internally scaled to +/- 15 V

Versatile Parallel Signal Processing

The Signal Blender Stereo splits your input into multiple parallel paths allowing independent control over two effects loops and the clean signal. Use it to blend effects in stereo or mono, split signals to three separate outputs, or combine multiple input signals into a single output with precision and clarity.

Each effects loop features a send jack and volume-controlled return, with phase invert toggles to correct phase issues caused by certain pedals. Trails switching ensures natural decay of time-based effects after bypassing, preserving tone integrity. The clean path can be switched on or off independently, with a dedicated volume control for perfect mix levels.

Switch between stereo and mono operation effortlessly—simply use TRS or TS cables as required. Enable mono input to stereo output mode using the internal dipswitch for expanded routing options.

Signal Blender Stereo combines advanced functionality, robust build quality, and intuitive controls to elevate your signal chain and unlock fresh sonic possibilities in any musical setting.
