The Rampage Bass 60 is a bass guitar amp with 60 watts of power in a kick-back design that gets your sound out to the crowd. It features an exclusive 12" speaker designed specifically for this amplifier. As a bonus, Rocktron's exclusive Dynamic Limiting eliminates worry about overloading and "woofing out" the speakers. Jam on and let the band know you're there! The Rocktron Rampage 60 offers a four band EQ section providing treble, middle frequency, middle level and bass. The frequency control knob adjusts the midrange EQ sweep. The Level control will adjust the overall output of the frequency - a very useful feature that allows the bassist to dial in all sorts of tones.
