Old Blood Noise Endeavors Expression Ramper – Used

Quick Product Summary

The Old Blood Noise Endeavors Expression Ramper is a compact expression controller designed to unlock new possibilities from pedals equipped with an expression input. Rather than controlling a parameter manually with a conventional treadle pedal, the Expression Ramper automatically moves between two user-defined expression positions.

This used example is in Good condition, showing visible signs of previous ownership and regular pedalboard use. With adjustable A and B positions, variable movement speed and multiple movement shapes, it can turn an expression-enabled delay, modulation, pitch or reverb pedal into a much more dynamic effect.

What Makes the OBNE Expression Ramper Special?

The Expression Ramper allows you to define two expression values — A and B — and automatically move between them. The Rate setting determines how quickly that movement occurs, effectively adding automated modulation to whatever parameter the connected pedal assigns to expression control.

Three movement styles provide different results. Triangle creates a smooth repeating sweep between A and B, Square jumps directly between the two positions, and One-Shot moves from one setting to the other when triggered. This makes the Ramper capable of everything from subtle parameter movement to dramatic rhythmic changes.

Who Is It For?

The Expression Ramper is ideal for musicians using pedals with expression inputs who want automated control without occupying the extra floor space required by a traditional expression pedal.

It works particularly well with delay time, modulation rate, pitch, reverb parameters, filter frequencies and effect mixes, making it useful for ambient, experimental, shoegaze, electronic and creative guitar setups.

No power supply is included with this used pedal.

FAQs

What does the OBNE Expression Ramper do?

It automatically controls the expression input of a compatible effects pedal, moving between two user-defined expression positions.

What are the A and B settings?

A and B represent the two expression values that the Ramper moves between. These could correspond to two delay times, modulation depths, pitch settings or almost any other parameter controlled by the connected pedal's expression input.

What does the Rate control do?

Rate determines how quickly the Expression Ramper moves between the A and B positions.

What is Triangle mode?

Triangle mode creates a smooth continuous movement between A and B and then back again, functioning similarly to an LFO.

What is Square mode?

Square mode jumps instantly between the A and B values rather than gradually moving between them, creating more pronounced rhythmic parameter changes.

What does One-Shot mode do?

One-Shot performs a single transition from one expression setting to the other when activated instead of continuously cycling.

Does it create audio effects itself?

No. The Expression Ramper does not process the instrument's audio signal. It controls the expression input of another compatible pedal.

What pedals can it work with?

It can work with many pedals that accept expression control, including compatible delay, reverb, modulation, pitch and filter effects.

Is the expression output configurable?

Yes. Internal configuration allows operation with standard TRS, reverse-polarity TRS and TS expression systems.

Why does expression polarity matter?

Different pedal manufacturers can wire expression connections differently. The configurable output helps the Ramper work with a broader range of equipment.

Does it replace a normal expression pedal?

For automated parameter movement, yes. However, it does not provide the same manual foot-controlled treadle operation as a conventional expression pedal.

Does an expression cable come included?

No. No expression cable is included with this used unit.

Can it run from a battery?

No battery operation is specified for the Expression Ramper, so it should be powered using a suitable external 9V DC supply.

Is a power supply included?

No. No power supply is included with this used unit.

What condition is this example in?

This example is graded Good, with visible signs of previous use consistent with a pre-owned pedalboard controller.
