Expression Slider is a fader for use with any pedal that has an Old Blood style expression input*. It is built for convenience and tactile experience, allowing external control where you need it - on the desk of your studio, velcroed to a guitar strap, or wherever else a TRS cable allows.

Expression Slider is entirely passive and requires no power supply.

*Expression Slider uses a TRS jack with tip connected to the wiper of a 50K slider, and ring and sleeve connected to the other terminals. We’ve confirmed that it works with all Old Blood pedals as well as pedals from Chase Bliss, Meris, Earthquaker Devices, Empress, Montreal Assembly, Red Panda, Strymon, EHX, and more.

Dimensions: 2” (width) x 3.75” (height) x 2” (depth).
