Mesa Boogie expands on the wildly popular Throttle Box overdrive pedal with the Throttle Box EQ. This tone monster adds a 5-band graphic equalizer to a killer drive capable of a plethora of modern drive tones. The HI/LO switch offers up a range of gain not found on your typical drive, and a global mid-cut switch scoops the midrange out of both sides of the pedal for blistering metal solo tones.
