HS-S Treble Booster

The Hornby-Skewes Treble Booster is a sought-after effect pedal known for its treble-boosting capabilities. Originally favored by Ritchie Blackmore, this pedal has been used in iconic recordings, providing a distinctive edge to guitar tones in live and studio settings. Musically, the HS-S offers a more aggressive sound compared to its predecessor, emphasizing mid-range frequencies when the guitar's volume is fully open. The tone can resemble a Wah sound but shifts as the pre-amp volume increases, allowing the amp's saturation to introduce rich harmonics. Finding the optimal settings requires adjusting the amp's pre-amp volume, particularly with clean amps like the Marshall Major, which may benefit from modifications for enhanced performance.
