the modified instrument, Garcia commissioned another custom guitar from Irwin with one caveat: "Don't hold back." During the Grateful Dead's 1974 European tour, Wolf was dropped on several occasions, one of which caused a minor crack in the headstock. Following filming of The Grateful Dead Movie (in which the guitar is prominently visible) a month later, Garcia returned it to Irwin for repairs. Throughout its absence, Garcia predominantly played several Travis Bean guitars, including the TB1000A (1975) and the TB500 (1976-1977). On September 28, 1977, Irwin delivered the refurbished Wolf back to Garcia. The wolf sticker which gave the guitar its name had now been inlaid into the instrument; it also featured an effects loop between the pick-ups and controls (so inline effects would "see" the same signal at all times) which was bypassable. Irwin also put a new face on the headstock with only his logo (he later claimed to have built the guitar himself, though pictures through time clearly show the progression of logos, from Alembic, to Alembic & Irwin, to only Irwin). Nearly seven years after he commissioned it, Garcia received his second custom guitar ("Tiger") from Irwin in the summer of 1979. He first employed the instrument in concert at a Grateful Dead performance at the Oakland Auditorium Arena on August 4, 1979. Its name was derived from the inlay on the preamp cover. The body of Tiger was of rich quality: the top layer was cocobolo, with the preceding layers being maple stripe, vermilion, and flame maple, in that order. The neck was made of western maple with an ebony fingerboard. The pickups consisted of a single coil DiMarzio SDS-1 and two humbucker DiMarzio Super IIs which were easily removable due to Garcia's preference for replacing his pickups every year or two. The electronics were composed of an effects bypass loop, which allowed Garcia to control the sound of his effects through the tone and volume controls on the guitar, and a preamplifier/buffer which rested behind a plate in the back of the guitar. Fully outfitted, Tiger weighed . This was Garcia's principal guitar for the next eleven years, and most played. In the late 1980s Garcia, Weir and CSN (along with many others) endorsed Alvarez Yairi acoustic guitars. There are many photographs circulating (mostly promotional) of Garcia playing a DY99 Virtuoso Custom with a Modulus Graphite neck. He opted to play with the less
