The classic guitar speaker began as a radio speaker before being modified for electric guitar amplifiers. Initially released as the G12, it was available in various colors. However, the Blue version, known as the T.530 and standard in Vox AC30 amps, cemented its legacy in guitar tone history.

Favored by renowned guitarists such as Brian May, the Blue is celebrated for its subdued attack, warm lows, mellow upper-mids, and luminous bell-like highs. Paired with an appropriate amplifier, it delivers rich definition and achieves exquisite musical compression when driven. For tone aficionados globally, the Blue sets the standard for guitar speaker excellence.
