BSM DM-T Fat Treble Boost

DM-T Fat Treble Boost BSM works only with original NOS germanium and silicium transistors !! They are hand selected for each pedal !! The DM-T is based on a germanium fitted special Booster from the late 60‘s. Here is a copy of this 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 Ambassador Treble & Midrange 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 original west European NOS 60s germanium transistors. 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 aprox. 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. User Manual
