Up your pedal game.

Add motion where there was none.

The Expression Ramper from Old Blood Noise Endeavors turns any pedal with an expression input into a living, breathing modulation source. Set two expression positions (A and B), then let the Ramper glide, pulse, sweep, or randomly wander between them — either once or forever. What used to require constant foot movement now happens automatically, musically, and precisely.

This is the secret weapon for ambient players, modulation lovers, and anyone who wants their pedalboard to feel less static and more alive.

Housed in a mini enclosure, it takes up almost no space while unlocking an entirely new layer of control across your board.

What It Does

• Move smoothly between two expression settings
• Act as an LFO for any expression-equipped pedal
• Create rhythmic sweeps, evolving textures, filter pulses, pitch movement, and ambient swells
• Run as a one-shot sweep or continuous modulation source
