The Old Blood Noise Endeavors Expression Slider HK is a compact and portable expression fader designed to give you hands-on control over any pedal or device with a standard expression input. With smooth operation, a tactile slider, and striking artwork by Oklahoma-based art duo Holey Kids, this utility device is the perfect companion for studio setups, live rigs, or anywhere you want direct control at your fingertips.

Unlike traditional expression pedals, the Expression Slider HK puts parameter control in a slider format, making it convenient to mount on a desk, console, mic stand, or even a guitar strap. No power is required — simply connect it with a TRS cable to your favourite pedal and start shaping your sound.
