The 2671 features a carved ash single-cutaway body with German carve edges, abalone purfling and cream binding mated to a set-in maple neck with a 22-fret ebony fingerboard with binding and mother of pearl vintage vine inlays 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 and a phase toggle for the neck pickup, a Tune-O-Matic style bridge and fancy stop tailpiece, speed knobs with pointers and Smooth Tuner machine heads.
Sometime around 1977 the Super 70 pickups were replaced with the new Super 80s. It's possible that at that time or perhaps at a later date the phase toggle was swapped out for a Tri-sound switch, but there is no documentation that verifies that conjecture.
The 2671S is a similar model with split block fretboard inlays and no phase switch. The 2681 Bob Weir is a related model with a double-cutaway body with truncated horns. The 2617 is a related Artist model with a double-cutaway body and split block fretboard inlays.
