First introduced in 1934 and enhanced later in 1939 Gibson's Super 400 set a new standard for large-body jazz guitars. Its 18 inch wide body gave it the cutting power to project through any big-band horn section. Introduced in 1939 the Super 400 Premier (400P) was the third version of the Super 400, it had a Venetian cutaway which meant a smaller neck block, shorter pickguard and shallower neck set than the first two iterations of the Super 400 design. This original Super 400 Premier was made from 1939 to 1941 - with some later models being shipped in 1943.
Gibson's Custom, Art and Historic division reissued the Super 400 in 1993 as the 1939 Super 400 model - in both cutaway (Premier) and non-cutaway versions as part of the Gibson Historic Collection. This reissue was fashioned from book-matched curly maple, the highly flamed maple back and rims were offset by a two piece figured maple with a mahogany center strip. The tops were tap-tuned spruce. The pegheads were hand-engraved and these guitars had "Super 400" logo on the heel cap and tailpiece. This reissue was made until around 1998.
