The Gibson L-6S Custom entry in this folder is, again, a close out line (in line with the Gibson Specials rationale - see the inside cover), with the models deletion announced in Gibson New a year earlier. However, it also fits the criteria for a limited edition test model (again see inside cover), in that it is offered here in two new finishes.
The L-6S had not been included in a US Gibson price list since January 7th 1980, and not in a US catalog since 1978. The text below is incorrectly copied from page 9 of the 1978 Gibson Quality / Prestige / Innovation catalog. Whilst the body specifications are identical, the neck specifications trip over themselves. They mention the maple fretboard on natural-finished guitars, and then get into a tangle in the wording. Of course, Natural finish is not even offered here. However two new finishes are offered, never having been previously available for the L-6S Custom: Wine Red and Silverburst. Like the existing Ebony and Tobacco Sunburst finishes, these were both supplied with an ebony fretboard.
The accompanying image, however is not taken from the 1978 catalog, and appears to be one not previously used by Gibson. Unfortunately, in lacking colour, it is hard to tell whether this is a guitar in the existing Tobacco Sunburst or the new Silverburst finish.
