RM Treble Booster

BOOSTER

The BSM RM model is based on the British Range Master unit produced between 1965 and 1969, as used by Eric Clapton in John Mayall's Bluesbreakers. Eric also used the booster when playing in the legendary group Cream. Its biting, powerful sound is clearly in evidence on the Bluesbreakers "Beano" album. Blues rocker Rory Gallagher, Heavy Rock pioneer Tony Iommi and Brian May from Queen were also heavy users of the orginal Range Master unit. The Range Master unit was also used by G. Tipton & K.K. Downing of the British heavy metal band Judas Priest in the late 1970s years to push its amps in full-tilt heaven. The long yearned for new edition, now issued under the name RM from BSM, includes the same OC44 germanium transistors as the the original 1965 version.
