The VX-C is based on the British V*X Bass & Treble Booster, made in the mid/late 60s. It’s a recreation, based on the second version of the booster, which was used by many bands those days.

The VX-T is based on the VX-C model, but with more gain, fattened highs and an adjustable mid range, instead of the bass range of the original for a more modern sound.

The RMG signature model is based on the original V*X Treble Booster and was modified to produce the clean “jingle jangle” sound of Roger McGuinn and the Byrds. With its almost unity gain, the RMG is the perfect booster for all clean, sparkling sounds (e.g. country), as well as for acoustic guitars.

The fine BSM V-TB, a replica of the old V*X TrebleBooster from autumn 1964, has finally made it from a custom order to a regular model. Roger McGuinn of the Byrds created his 1960´s sizzling "jingle-jangle" trademark sound with the V*X TrebleBooster along with his 12-string Rickenbacker guitar. With the "Bass Boost" switch, the bass frequencies can be raised by +10dB, resulting in a beautiful sparkling tone, Tom Petty and his sideman Mike Campbell comes to mind.
Let´s work out the differences between the BSM V-TB and RMG models. The RMG is based on the V*X treble & bass booster that was released after the V*X treble booster. While the RMG has a pot to fine-tune the high-end, the VT-B has preset shimmering highs and BSM added a bass mode switch with two settings to get a more modern sound in the direction of Tom Petty & the Heartbreakers.
