Randall RM20B 1x12 Combo Black RAN0035

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.
