You choose the tone! With fourteen modules to choose from and more in the works, 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.
A bright switch is included directly under each Bass control. Each preamp module houses two 12AX7 tubes which can be easily changed or replaced. Use the thumbscrew to remove or secure each module to the front panel of every MTS amplifier.
Based on the preamp circuit of a hot rodded Marshall® Super Lead. We give the classic Super Lead circuit a bit more gain and punch. It will handle anything from Zeppelin to Zakk.
