Purchased by David Gilmour from a guitar dealer on Denmark Street, London's Tin Pan Alley, in the mid-seventies, the instrument is one of a very small number of likely custom ordered guitars made using the existing Les Paul Custom platform but incorporating a highly figured all maple body and a control cavity routing on the top rather than back. This positioning of the cavity was only seen on Gibson’s Les Paul Recording model. Of an equally rare and custom variant, Gibson had incorporated stereo circuitry on this specific instrument. Over the years, the guitar has undergone numerous alterations to accommodate Gilmour’s changing requirements. These changes included upgraded electronics and re-wiring to accommodate “full stereo performance” across its entire sonic spectrum.
