Randall MTS Series Combos

A half-stack's nightmare! Designed for ultimate flexibility, this revolutionary fully loaded 100 watt modular tube combo provides easy mobility without sacrificing the punchy tone of a closed back cabinet. Because it’s an MTS series amp and can be loaded with any number of tube preamps, we had to design a cabinet that would work well for both rock and metal, as well as spankin' country and blues.

To do this we designed the amp with a dual back option. The amp comes from the factory basically sealed giving you the punch and tightness of a closed 2 x 12, but it also includes a 1/3 removable top panel to achieve the looser, more boomy low end found in traditional semi-open back combos.

Don’t get us wrong, this seriously powerful combo was designed to rock, but it will definitely dish out serious tone across each genre of music.

Small but mighty! Continuing to build on the success of the highly flexible MTS Tube Series, Randall introduces the RM20 modular tube combo. Built specifically for the professional gigging and recording musician, this EL84 powered combo performs equally well on stage or in the studio.

Featuring a single modular channel with a footswitchable tube boost, the RM20 can take a lower to mid-gain module from pristine clean to sustaining lead tone at the click of a switch by simply activating the included tube boost function. Use the tube boost gain control to add a desired amount of additional saturation then adjust the boost level control for the desired boost volume.
For all modules, especially the higher gain tones, the tube boost function can be used as a volume boost without adding additional saturation by simply rolling out the boost gain and adjusting the amount of boost volume.

For studio use the RM20 features the XLR “Mic Eliminator” direct output circuit as well as a speaker on/off “Standby” switch for silent recording to lay down real authentic tube guitar tracks without disturbing the neighbors.

This combo can be ordered with any combination of 13 tube preamp modules, providing an extremely wide-range of vintage to modern tube amp tones.
