Welcome to the most versatile 3-channel head ever created. Randall's new flagship sets the standard for all tube designed heads. The RM100M is tradition and technology rolled into one amplifier. First, you have 3 independent channels that can be loaded with your choice of any of the available tube preamp modules. Set this head up with the specific tones that you choose, and expand your arsenal anytime you like. Don't purchase an amp because you only like it's clean or hi-gain tone, build an amp with your clean, rhythm, and hi-gain tone, with the option to expand.
Modules not included.
Enjoy the ease of replacing your power tubes anytime you like, with the very user friendly power tube bias section. If a tube fails, no problem, the amp will kick that tube out of the circuit, and a small LED will light by the tube that fails.
Connect your RM100M to any MIDI capable external processor, and program individual effects to each channel. With the MIDI in/thru, simply select your channel and external effect, using the included RF3 MIDI footswitch. The footswitch will select both the RM100M channel and effect you want at the same time.
Thew RM100M features a modern metal grill front panel.
So, if you need the volume and power only a head will offer, choose one that will adapt to your styles.
