decorated model but the promotional photo from the Alvarez Yairi catalog has him holding the "tree of life" model. This hand-built guitar was notable for the collaboration between Japanese luthier Kazuo Yairi and Modulus Graphite of San Rafael. As with most things Garcia, with his passing, the DY99 model is highly valued among collectors. In 1990, Irwin completed "Rosebud", Garcia's fourth custom guitar. It was similar to his previous guitar Tiger in many respects, but featured different inlays and electronics, tone and volume controls, and weight. Rosebud, unlike Tiger, was configured with three humbuckers; the neck and bridge pickups shared a tone control, while the middle had its own. Atop the guitar was a Roland GK-2 pickup which fed the controller set inside the guitar. The GK2 was used in junction with the Roland GR-50 rack mount synthesizer. The GR-50 synthesizer in turn drove a Korg M1R synthesizer producing the MIDI effects heard during live performances of this period as heard on the Grateful Dead recording Without a Net. Sections of the guitar were hollowed out to bring the weight down to . The inlay, a dancing skeleton holding a rose, covers a plate just below the bridge. The final cost of the instrument was $11,000 (). In 1993, carpenter-turned-luthier Stephen Cripe tried his hand at making an instrument for Garcia. After researching Tiger through pictures and films, Cripe set out on what would soon become known as "Lightning Bolt", again named for its inlay. The guitar used Brazilian rosewood for the fingerboard and East Indian rosewood for the body, which, with admitted irony from Cripe, had been taken from a 19th-century bed used by opium smokers. Built purely from guesswork, Lightning Bolt was a hit with Garcia, who began using the guitar exclusively. Soon after, Garcia requested that Cripe build a backup of the guitar. Cripe, who had not measured or photographed the original, was told simply to "wing it." Cripe later delivered the backup, which was known by the name "Top Hat". Garcia bought it from him for $6,500, making it the first guitar that Cripe had ever sold. However, infatuated with Lightning Bolt, Garcia rarely used the backup. After Garcia's death, the ownership of Wolf and Tiger came into question. According to Garcia's will, his guitars were bequeathed to Doug Irwin, who had constructed them. The remaining Grateful Dead members disagreed – they considered his guitars to
