Bluesman BB King had been endorsing Gibson guitars throughout the 1960s and 70s, but it was not until 1981 that his signature "Lucille" model was finally available. In fact King had been playing the existing top-of-the-range thinline, the ES-355TDSV for quite some time (he talks about the stereo 355 here) but would stuff paper into the f-holes to reduce feedback. The BB King Standard and BB King Custom had no f-hole.
The first mention of a signature model appears in an article about BB from the Gibson '79 promotional magazine:
One name is always associated with him, though. It's Lucille. From the beginning, B.B. King has played Gibsons. He has made the Gibson ES-3S5 famous. He now plays a custom model that Gibson made specially for him, it is called Lucille and is one of a kind. As he did more than 30 years ago, B.B. King helps make the Gibson name great.
The BB King Custom and Standard were first included in price lists in April 1981, alongside the ES-355TDSV. The list price of the Custom was $1789, followed by the ES-355TDSV at $1599, finally the BB King Standard at $1389. The first two had gold-plated hardware, block inlays, and ebony fingerboard and a varitone control, the latter was simpler, with chrome hardware and dot inlays. The the final inclusion in a price list of the ES-355TD SV was 1st January 1982 however, and in many ways the BB King Custom "Lucille" superceded it. These were expensive guitars, but were produced to a very high standard at the legendary Gibson Kalamazoo plant, in Michigan, USA.
The precise differences and specifications for these three models are summarised below.
The following description of the BB King Custom comes from the 1983 Gibson catalog:
