Treble Booster

A treble booster is a type of effects pedal made famous in the 1960s by guitarists such as Brian May, Tony Iommi, Marc Bolan, and others. It was generally the first pedal in a guitarist’s signal path, and very often was the only effect before the amplifier. The name “treble booster” is a bit of a misnomer, since a treble booster really acts like more of an upper-mid boost that adds harmonics and a light overdrive rather than increasing treble. Because the sonic energy is focused in the upper mids, treble boosters can sound great into an amplifier that is just starting to break up or one that is already somewhat distorted, unlike other kinds of “dirt” pedals which can sound muddy into distorted amps.
