he BSM SPECTRUM Fuzz-Booster is our tribute to Tommy Bolin, guitar wizzard of the 70's, that was not only well known because of his marvelous guitar playing as a studio guitarist on Billy Cobham's spectacular "Spectrum" jazz fusion album from 1973, he was also a worthy follower for Ritchie Blackmore on Deep Purples "Mk_IV". All the time Mr. Bolin had a punchy and "in the face" sound which he created with a Sam Ash Fuzzz unit that had a controlable, treble-boosty character. The BSM "Spectrum" is an copy of the Sam Ash Fuzzz that Tommy Bolin used, down to the oddest details like the "attack" control that can smoothly blend from treble boost to fuzz, while the "spectrum" control manipulates the tone spectrum up to unbelieveable almost six octaves - because of this it should be very easy to find the sound you are yearning for.

Spectrum Fuzz Booster

Brian May from Queen used in his early days the British Range Master Germanium Treble Booster, a unit produced between 1965 and 1969. This model is rebuild as RM by BSM. In mid-phase from Queen, BrianMay switched to a silicon Treble Booster design for more bite, now reproduced by BSM with orginal silicon transistor and called BM-Q special. The same unit fitted with volume control called BM-Q.

 BM-Q special Treble Booster 

The BSM HS model is based on the short-lived early edition British HORNBY-SKEWES unit produced, as used by Ritchie Blackmore, the brilliant and impulsive guitarist of Deep Purple. The unit produces a powerful and biting sound that was used to help create the epochal masterpieces e.g. "Deep Purple In Rock" and "Fireball". The long yearned for new edition, now issued under the name HS from BSM, includes the same germanium transistors as the 1965 version. The HS-Custom model includes a volume control (like Blackmore's modification).

HS Treble Booster

As a follow-up of the short-lived germanium-transistor loaded early issued Hornby-Skewes Treble Booster, now the 1967 version, equipped with a silicon transistor, appears on the scene under the BSM brand HS-S. With additional volume control like Blackmore´s modified unit as HS-S Master available.

HS-S Master Treble 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.
