The BSM VX-T model is based on the british Vox Treble & Bass booster, made in the late 60's and used by many british bands at this time. Here is an almost identical copy of the second issue of this Vox unit, but with increased gain and a slightly modified tone network, pronouncing the mid frequencies and making the VX-T the perfect treble-midrange booster. So the sound of the VX-T is placed in between the VX-C Classic Treble&Bass booster and the RMG Treble Booster. The VX-C Classic offers a more vintage orientaded tone control with some good low end, while the RMG adds more twang and spank to the tone. The VX-T model includes a tone control which allows an extraordinary amount of versatility.
