Used Ernie Ball Expression Overdrive Effect Pedal

Used Ernie Ball Expression Overdrive in great condition—an expressive drive pedal that lets you sweep gain with an onboard treadle for dynamic control from subtle grit to singing sustain. Dial in your tone with intuitive Drive, Tone, and Level controls, then ride the expression for real-time boosts and overdrive transitions. Built in a rugged metal chassis and powered by standard 9V DC, it’s a versatile upgrade for pedalboards needing hands-free drive control.
