BSM Treble Booster Model FireBall

This treble booster was manufactured for only three years, from 1967 to 1969, and was based on the Hornby Skewes used by Ritchie Blackmore during his Deep Purple days. It is a faithful reproduction of the 1967 model, with a high standard of selection of hard-to-find parts such as European-made germanium transistors. It has a powerful sound with a bite that you hear in famous hard rock albums. By controlling the guitar volume, you can enjoy lead tone to crunch sound. It is powered by a 9V dry cell battery only.
