Old Blood Noise Endeavors Expression Ramper HK

Take Full Control of Your Sound with the Old Blood Noise Endeavors Expression Ramper HK

The Old Blood Noise Endeavors Expression Ramper HK is a powerful utility pedal designed to breathe life into your effects setup by automating expression control with precision and creativity.

Instead of relying on static settings or manual tweaking, this compact unit allows you to program smooth, evolving sweeps between two expression values - transforming the way your pedals respond in real time.

Ideal for musicians who want to push beyond conventional modulation, the Expression Ramper HK can create rhythmic pulses, gradual filter sweeps, or unpredictable parameter shifts. Whether you're shaping ambient textures, adding movement to delays, or morphing gain stages mid-performance, this pedal opens up a new dimension of sonic exploration.

Built with the experimental spirit Old Blood Noise Endeavors is known for, it integrates seamlessly with a wide range of expression-compatible pedals, making it an essential tool for guitarists, synth players, and sound designers alike.

• Expression Control Pedal, with storable settings and tap tempo
• Footswitch activated motion, create modulated effects on the fly
• Ramp between the two user-defined expression control settings (A and B)
• 6 waveforms for movement between settings (alternative wave shapes accessibly by pressing the TAP button while changing the shape toggle)
• Triangle - linear motion between A and B starting and ending at a and B at halfway on the LFO cycle o Square - snaps between A and B spending half of the LFO cycle in each position
• 1 Shot - moves linearly from A to be or B to A, depending on the starting point o Smooth Random – repeatedly moves to a random spot between A and B in linear fashion
• Sharp Random - immediately moves to a new random spot between A and B at the start of each cycle
• 1 Shot Random - moves linearly from either A to B or B to A and then stops
• Rate control or Tap Tempo button - for quickly and accurately inputting the desired movement speed
• 50K digital potentiometer compatible with the most expression-control-capable pedals on the market
• User-configurable EXP output (TRS, TRS reverse polarity or TS) 
• LED indicates which setting is currently active
• Powered by regular 9 V DC PSU  (centre -, 2.1 mm, ~50 mA current draw)
