Expression Ramper

The Old Blood Noise Endeavors Expression Ramper is a versatile expression controller designed to automate expression control and create innovative sounds with pedals featuring an expression input. Here are the technical specifications and features:

- Shape Toggle: Allows the user to determine the LFO motion with options for triangle, square, or one-shot shapes.
- Assignable Knob: Enables setting of A position, B position, and LFO Rate.
- Footswitch: Activates expression output motion.
- Internal Configuration: Supports TRS, TRS reverse polarity, and TS configurations, with the ability to replace the built-in 50K digipot with 10K or 100K versions.
- LED Indicator: Displays the active setting.
- Power Requirement: Requires a 9V DC center negative 2.1mm jack power supply capable of 20mA (not included).

The Expression Ramper allows users to pick two expression settings and move between them in one motion or as a continuous LFO activated by a footswitch. It offers three different ways to move between settings: linear Triangle wave sweep, instant Square Wave jumps, and a one-shot sweep. The speed of the LFO and one-shot movement is set via the Rate knob.

The pedal is suitable for a wide range of effects pedals and can be configured for different polarity or types of expression pedal simulation using internal jumpers. Additionally, the internal 50K digital socketed potentiometer can be replaced with 10K or 100K values to tailor the pedal for specific expression- enabled devices.

The compact enclosure ensures that the Expression Ramper can be easily integrated into any setup, offering a simple and intuitive way to unlock a wide range of sound possibilities.
