You choose the tone! With fourteen modules to choose from, having a new amp is as simple as plugging in a new module. Start with as few as one, or as many as you like and have all your favorite tones right at your fingertips. All modules can be used for the RM4 preamp, RM combos and RM heads. All modules utilize the same panel layout, which includes Gain, Bass, Mid, Treble and Master controls.

(Based on the preamp circuit of a Bogner® Ecstasy red channel. An all around great hi-gain tone with tight low end and cutting mid-range. It will cover any rock to metal tone. This one screams!)
