Randall TOPA MTS Series Tube Preamp Module - Top Boost

Made specifically for Randall's MTS Series Heads & Combos, these preamps modules make having a new amp 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.

The Top Boost module is based on the preamp circuit of a Vox® AC30TB with a little more kick in the front end. The Top Boost has a chimy hi-end that will handle anything from classic Petty, to Brian May to modern Lenny Kravitz.

All modules utilize the same panel layout, which includes Gain, Bass, Mid, Treble and Master controls, with a bright switch 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.
