Description

Edit description

Treble boosters - simultaneously boosting gain and the high end of the tonal spectrum, whilst attenuating lower frequencies - have always been an integral part of Brian May's signal path, from Queen's earliest recordings to his current stadium-sized setup, fly-in and recording rigs, and are an essential tool for any guitarist wishing to achieve a focused, cutting, overdriven sound, with clear note definition and string clarity.

The Treble Booster Classic (TBC) is an elegant and compact, multi-mode foot pedal designed by British electronics guru Nigel Knight of Knight Audio Technologies, that combines three separate, uniquely voiced circuits that faithfully replicate the maestro's most recognisable tones from the 70's, 80's and 90's, providing modern guitarists with the opportunity to dial in the distinctive sound of their favourite May-era, or to explore their own new musical horizons.
