BSM VX-C Classic


Sold out.

The BSM VX-C Classic model is the most authentic copy of the british Vox Treble & Bass booster from the late 60's, used by many british bands at this time. It offers the original tone network and gain from the original, to make it the perfect copy of this out-of-production stompbox. The VX-C Classic model includes a tone control, that allows an extraordinary amount of versatility from a wooly bass tone up to a sparkling high-end vintage sound. It´s also possible to produce the sound of a Wah-Wah pedal, set to a fixed middle position. So you can create the sound of Michael Schenker during his work with UFO or Mick Ronson, a famous guitarist in the early 70s backing band called SPIDERS of David Bowie. In comparison to it´s "hot brother", the VX-T, the VX-C Classic offers less gain and a more old-style tone control, while the VX-T is more focussed to pronounce the mid frequencies. Another sibling of the BSM VX family is the RMG, the custom model for the typical "jingle jangle" Roger McGuinn sound of the 60´s, the perfect booster for all clean sounds.


Almost all british rock guitarists using singlecoil pickup guitars, used some type of treble booster from the late 60's to the mid 70's. At the end of the seventies, these boosters were replaced with a new circuit from Japan, the socalled "Tube Screamer" and other similar overdrive circuits. These were based on the old boosters and therefore had a very similar frequency response. The treble boosters on the other hands side, sadly fell into oblivion, despite their unique and inimitable sound. It is of interest to note, that both Mick Ronson & Michael Schenker used the Wah-Wah pedal, set to a fixed mid-position as a booster. Mick Ronson used a 200 watt Marshall Major stack, while Michael Schenker used 50 watt Marshall stacks.


The VX-C Classic Booster is 100% true bypass and inserted between the guitar and the amplifier, not into the FX loop. The magical tone is achieved by the interaction between guitar pickup, booster and amplifier. The unit is powered by a single 9 volt battery with a current consumption of aprox. 50 uA. The average output level is 1dBm, the maximum output voltage when the strings are strucked really hard is 2V max. Note: The negative pole of the battery is ground !
