Used Ernie Ball Expression Overdrive Effect Pedal

Ernie Ball's Expression Overdrive pedal delivers rich, responsive overdrive tones with foot-sweepable control for real-time sonic shaping. This used unit is in good condition and features all-analog circuitry, a sweepable gain/volume blend via the treadle, and a built-in buffer. Housed in a rugged aluminum chassis, it's perfect for expressive guitarists seeking smooth, dynamic gain control on stage or in the studio. Powered by 9V DC (center-negative), it integrates seamlessly into any pedalboard setup.
