Unlock new sonic possibilities with the OBNE Expression Ramper Folded from Old Blood Noise Endeavors. This innovative yet straightforward device automates expression control, allowing you to create dynamic, evolving sounds with any pedal that features an expression input.

Main Features

• Store and recall two expression presets (A and B)
• Footswitch-activated modulation for real-time effect changes
• Smooth ramping between preset settings
• Choice of triangle, square, and one-shot wave shapes for movement
• Adjustable rate control to set modulation speed
• Configurable output: TRS, TRS reverse polarity, or TS
• LED indicator showing current active setting
• Powered by standard 9 V DC PSU (centre negative, 2.1 mm plug, ~50 mA current draw)

How It Works

The Expression Ramper lets you select two expression positions and move between them either continuously or in single sweeps. Simply connect it to your expression-enabled equipment, set your first expression value at position A, and your second at position B. Engage the footswitch to modulate between these points using different wave shapes:

• Triangle mode: smooth, linear sweep between positions A and B (LFO)
• Square mode: instant jumps between settings (LFO)
• One-Shot mode: single sweep triggered with each footswitch press

Use the Rate control to tailor the tempo of the modulation precisely to your performance needs.

Endless Creative Potential

Transform your gear with expressive modulation:
- Create Whammy-style octave glides on pitch-shifters
- Generate rhythmic phaser step-filter sequences
- Produce swelling feedback patterns on delays

With fully configurable polarity and potentiometer values (50K default, replaceable with 10K or 100K), the Expression Ramper can be custom-tailored to suit keyboards, synthesizers, vintage units, or rare expression-enabled devices.
