The 2681 is a Professional series solid body electric guitar model introduced by Ibanez for around 1976 (possibly in 1975). It was made in Japan by FujiGen. It is a signature model created for Bob Weir of the American rock band Grateful Dead.
The 2681 features a carved ash top with German carve edges, abalone purfling and cream binding on a double-cutaway ash body mated to a set-in maple neck with a 22-fret ebony fingerboard with binding and mother of pearl vine position markers which are continued on the large scroll headstock. Components include a pair of Super 70 humbucking pickups mounted in black pickup rings with individual volume and tone controls, a Tune-O-Matic style bridge and stop tailpiece, speed knobs with pointers and Smooth Tuner machine heads. At least one catalog mentions that the 2681 has a phase switch, but that was either an error in the catalog or a planned feature that never made it to production.
For 1977 the Gibraltar bridge with sustain block embedded in the body and the slotted Gibraltar tailpiece with scalloped "cloud" ornament were introduced, along with new Super 80 "Flying Finger" pickups, a bone and brass nut and VelveTune machine heads. For 1978 the knobs were replaced with Sure Grip knobs with rubber grip insert.
The 2680 is a similar model with a dot fretboard inlays. The 2617 is a related model with an Artist body shape with longer horns.
