Precise Control over Your Gain Levels

Ernie Ball's Expression Overdrive effects pedal delivers a transparent overdrive that is completely variable via the pedal's foot treadle. Pulling the pedal all the way to the heel position offers a clean tone that won't color your guitar's natural signal. As you move the treadle forward, the Expression Overdrive begins piling on the gain. Controls for tone and drive dial in your sound, while the boost knob sets the overdriven signal's total output. Take all these together, and you can easily see just how the Ernie Ball Expression Overdrive lets you determine exactly how gritty your tone is.

Features:

• Overdrive pedal with foot-variable gain levels
• Drive and tone controls dial in your sound
• Boost knob determines the pedal's output from unity to +6dB
• Built from extremely durable aircraft aluminum
