BSM DM-T Treble Booster


Sold out.

 The BSM DM-T model is based on the Winston Treble Booster made in England in the late 60's, and was used by some british bands at this time. Here is a true copy of the Winston circuit but with the nice addition of a very versatile frankenstein tone-control system: for the treble and mid tone-control the circuit of the almost forgotten Apollo booster is used while for the bass tone-control the circuit of a modified VOX booster will comfort your ears. In comparison to the technical similar but more gently sounding OR Treble & Bass Booster, the DM-T produces a harder sound without getting shrill. It fits perfectly the classic beat and rock sound but is also a good mate for funky or country rock music. The DM-T is loaded with the original NOS 60s germanium transistors like the Winston Treble Booster was.

Almost all British rock guitarists using single coil pickup guitars used some type of germanium booster from the late 60's to the mid 70's. By the end of the seventies, these boosters were replaced by a new circuit from Japan, the so called Tube Screamer and other similar overdrive circuits. These were based on the old boosters and therefore had a very similar frequency response. The germanium boosters on the other hand, sadly fell into oblivion despite their unique and inimitable sound.

The DM-T Booster is inserted between guitar and 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 9V battery with a current consumption of approx. 350 uA. The average output level is 7dBm, the maximum output voltage when the strings are struck really hard is 5V max. Note: The positive pole of the battery is ground.
