Details of two entry level Gretsch guitars, the Gretsch Corvette 6135 and Clipper 6186 guitars.
The Clipper was the thinnest of Gretsch's hollowbody models, with a width of just 1 3/4" - "extra thin for ease of playing".
The Corvette pictured is a dual pickup model, in Shaded Sunburst. In this catalog, this is the only variant listed. Previously single and dual pickup guitars were available, aswell as a stop tailpiece (non-vibrato) version. Note also the new headstock design. Compare this guitar with the Gretsch Corvette in the 1965 Gretsch catalog.
These were the least expensive Gretsch electric models. The solid body Corvette was listed at $225, whilst the single pickup hollow body Clipper was priced at $185 (US prices, April 1968).
