HS-S Master Treble Booster

The BSM HS-S is a silicon transistor-based treble booster, developed as a successor to the earlier Hornby-Skewes model featuring germanium transistors. This 1967 version delivers a bright and articulate boost, enhancing your guitar's high frequencies for a more pronounced sound. The HS-S includes an added volume control, allowing for greater flexibility in shaping your tone. This feature is reminiscent of Ritchie Blackmore's modified units, making it a practical choice for players seeking to fine-tune their boost levels.
