HS-C Custom Hornby-Skewes Treble Booster

The BSM HS-C Treble Booster is a modern recreation of a legendary British tone-shaping tool from the golden age of rock guitar. Inspired by the iconic Hornby-Skewes unit used by the legendary Ritchie Blackmore of Deep Purple, this pedal delivers the same biting, powerful sound that defined the band's seminal early albums. Powered by carefully matched germanium transistors, the HS-C recreates the unique frequency response and dynamic character of the original. When cranked, it unleashes a thick, saturated lead tone that cuts through the mix with authority, yet retains the nuance and clarity of your guitar's single-coil pickups. Backed off, it provides a wide range of rich, touch-sensitive crunch tones. What makes the HS-C so special is its ability to interface seamlessly with vintage tube amps. By restoring the high-end sparkle that often gets lost when an amp is driven into saturation, it allows the full frequency spectrum to shine through, minimizing the need for excessive presence control. Pair it with a Fender Deluxe, Vox AC30, or classic Marshall, and prepare to be transported back to the glory days of British rock. Whether you're chasing Blackmore's singing lead lines or searching for that elusive vintage crunch, the BSM HS-C Treble Booster is a must-have tool for any serious guitarist seeking to unlock the secrets of the past while carving out their own voice in the present.
