This classic guitar speaker actually started life as a radio speaker that was modified specifically for use in electric guitar amplifiers. In its original G12 guitar speaker incarnation it appeared in several colour variations, but it was the Blue version, known as T.530 and fitted as standard into Vox AC30 amps that secured its place in guitar tone history.

The Blue found favour with notable guitarists like Brian May due to its glorious dampened attack warm lows mellow upper-mids and brilliant bell-like top-end. When coupled with a suitable amplifier it evokes rich definition and develops beautiful musical compression when pushed. According to tone enthusiasts worldwide, the Blue is the benchmark for guitar speaker perfection.
