The Old Blood Noise Endeavors Expression Slider is a fader for use with any pedal that has an Old Blood style expression input (see details below). Simply use a TRS cable to plug the Expression Slider into the Expression input and use the slider as you would a knob or expression pedal. Suggested uses: strap it to your mic stand to adjust your favorite setting without bending down, keep it at your studio console to control a parameter while tracking, use the indicators to mark your favorite settings, or simply replace a knob control with a slider because let's face it: sliders are cool. Unsuggested uses: Unintended excess weight from use with foot while standing may cause damage to the device. Read: Don't use your foot.

Details: the Expression Slider uses a TRS jack with tip connected to the wiper of a 100K slider. Old Blood Noise confirmed that it works with all their other products, as well as pedals from Chase Bliss, Meris, Earthquaker Devices, Empress, Montreal Assembly, Strymon, EHX, and Boss. It will not work with TS style expression inputs such as Line6 without an additional TRS splitter cable.
