Old Blood Noise Endeavors Expression Ramper Folded Expression Controller Pedal

The Old Blood Noise Endeavors Expression Ramper Folded Expression Controller is a compact, hands-free way to bring movement, modulation and life to any expression-enabled pedal, synth or keyboard. Instead of rocking a treadle, you set two expression positions and let the Ramper automatically sweep, step or glide between them, turning static sounds into evolving textures, rhythmic pulses and dramatic one-shot sweeps.

Housed in a neat folded enclosure, the Expression Ramper gives you two user-definable expression points, three modulation modes and a simple control layout that drops straight onto any board. From slow filter swells and auto-whammy dives to choppy trem-style steps and animated delay feedback, it transforms your existing gear into something far more expressive without taking up much space.

At its core, the Ramper is all about creative control. You can store two expression settings, labelled A and B, then decide how the pedal moves between them using triangle, square or one-shot modes. With flexible TRS, reverse TRS and TS output options via internal jumpers, it is ready to talk to a wide range of modern and vintage expression-controlled devices, including more specialist units that can be tricky to match with standard expression pedals.

Whether you are a guitarist wanting automatic filter sweeps, a synth player looking for LFO-style modulation without tying up a hand, or a sound designer chasing evolving drones and glitchy steps, the Expression Ramper Folded Expression Controller offers a powerful, performance-ready way to automate your favourite parameters.

Automated Expression Between Two Positions

The Expression Ramper lets you define two distinct expression points, A and B, then automatically moves between them. This means you can dial in the perfect minimum and maximum settings on your connected pedal or synth, and have the Ramper handle the motion. It is ideal for creating evolving pads, dynamic ambience or repeatable sweeps that would be difficult to perform consistently with a traditional treadle.

Three Distinct Modulation Modes

With triangle, square and one-shot sweep modes on tap, the Ramper can behave like an LFO, a step sequencer or an automatic envelope-style sweep. Triangle mode gives you smooth, continuous modulation, square mode delivers abrupt jumps for rhythmic, stepped effects, and one-shot mode performs a single A to B sweep when engaged. This flexibility lets you cover everything from subtle movement to bold, attention-grabbing shifts.

Compact Folded Enclosure

The folded enclosure keeps the Expression Ramper small, sturdy and easy to place on any pedalboard or desktop rig. Its footprint is far smaller than a full-sized expression treadle, yet it offers far more complex movement options. This makes it a great choice for players who want deep control and animation without sacrificing valuable space.

Wide Compatibility and Internal Configuration

Thanks to its TRS, reverse polarity TRS and TS output options, along with internal polarity selection jumpers and a socketed digital potentiometer, the Ramper can be tailored to work with a broad range of expression-enabled devices. Whether you are controlling modern pedals, classic units or more esoteric gear, the internal configuration options help you match response and feel to your setup.

• Dual A and B Expression Settings - Store two independent expression positions and let the Ramper move between them, so you can define the exact range of motion for your effects and recall it instantly for consistent, repeatable performance.
• Multiple Modulation Modes - Choose between triangle, square and one-shot sweep modes to turn any compatible pedal into an LFO-modulated effect, a step sequencer-style tool or an automatic sweep generator for dramatic transitions.
• Flexible Output and Internal Jumpers - TRS, reverse TRS and TS output options, along with internal polarity selection jumpers and a socketed 50k digital potentiometer, allow you to match the Ramper to a wide variety of pedals, synths, keyboards and specialist expression-controlled devices.
• Compact, Footswitch-Controlled Design - A soft-touch footswitch and small folded enclosure make it easy to drop the Ramper into any rig, giving you hands-free, automated expression control without the bulk of a traditional treadle pedal.
