Randall MTS Amp Specifics

Let's cover the different amps and the specific features that are available in the Randall MTS series.

Randall RM Rack Gear

The rack setup features the Randall RM4 preamp and a separate tube power amp the RT2/50. The RM4 houses 4 of the Randall preamp modules for the ultimate in tone flexibility. Imagine going from ultra clean to Vox breakup to Marshall Plexi to Boogie Recto tones in one preamp.

  • Four independent channels (with your choice of vintage to modern voiced preamps)
  • Parallel effects loops with front panel mix control
  • Series effects loop
  • MIDI in / thru
  • Pre and post loop outputs
  • Two 12AX7's buffer the effects loop
  • Eleven 12AX7 tubes (when used with 4 modules)
  • Four button MIDI selectable footswitch
  • Front & rear panel inputs

    The Randall RT2/50 is a 2 channel power amp with channel 1 featuring 6L6's and channel featuring EL34's. Each channel can be changed via midi making it easy to match the appropriate power section to each module. Or setup the power amp for 100 watts stereo mode.

  • 50/50 watts mono (Channel Switching mode)
  • 100 watts stereo (Normal stereo mode)
  • Channel 1- Ruby 6L6's (Standard)
  • Channel 2- Ruby EL34's (Standard)

    Randall RM Heads

    The heads come in 2 flavors, 50 watts and 100 watts. The 100 watt models feature 3 preamp slots while the 50 watt version features 2 preamp slots plus reverb. The 100 watt versions can also change channel via midi while the 50 watt head uses the typical amp channel select foot switch.
