some of the most popular amplifier set-ups were British Marshalls and Vox's.....often with multi-speaker cabinets. Players like Tony Iommi, Ritchie Blackmore, Brian May etc, carved their signature sounds on stage and in the studio with these rigs, and in order to deal with the over-powering bottom end, they made use of 'The Treble Booster'. Treble Boosters add top end or higher frequencies to the guitar tone, and depending on how the amp is set up, some much desired overdrive.
