The Original.

Heard on:

The Beatles, Queen, U2, Radiohead, Suede, Foo Fighters, Tom Petty, Stone Temple Pilots, The Shadows, Portishead, James Bond theme, vintage Vox AC30 amps

The one that started it all. As the de-facto speaker of the first Vox AC30s, the Celestion Blue is etched in history as the sound of the 60's British Invasion. It's the voice of rock n roll.

It has a distinctive growl and warm body, with a laid back alnico feel of a dampened attack, and a famously chiming bell-like top-end. Driven hard, it oozes rich definition and develops a beautiful musical compression.

Its unique shimmering presence can also paint rich atmospheric textures; from lush euphoric soundscapes (U2) to smoky, mysterious noire (Portishead, James Bond), or vast, scorching spaghetti westerns (Ennio Morricone).

      Yes, although it's a very close fit in the enclosure, it does install fine and is a great upgrade for this amp.
