The Epiphone NOEL GALLAGHER SUPERNOVA was introduced in 1997 and made until 2005. The Supernova was originally available in Ebony, Cherry, Metallic Light Blue (Manchester City Blue), and Vintage Sunburst finishes. Noel Gallagher’s own modded/original “Union Jack” Epiphone Sheraton had a frequensator tailpiece and mini-humbuckers but his Epiphone signature model had a regular Tune-o-matic tailpiece and full-size Epiphone humbuckers (like later stock Sheratons). The Epiphone Supernova was made in Korea, in Samick and Peerless factories and there are slight differences between Samick and Peerles made body shapes. The neck radius is 16",

The Epiphone Union Jack Supernova (with Union Jack graphic on the body) is listed as a different model to the regular Supernova in the Epiphone 2002 catalog - with a maple neck (instead of mahogany) and different pickups - but in the 2003 catalog the specs are identical (except for the finish).
