1989 Gibson SG90 Electric Guitar - Alpine White (7 lb 10 oz)

Serial Number:  80648523
Weight:  7 lb 10 oz

This 1989 Gibson SG90 in Alpine White represents Gibson's short-lived answer to the superstrat era—a highly spec'd, single-humbucker SG variant built for speed and modern performance. Featuring beveled Honduran mahogany body, graphite-reinforced slim taper neck, ebony fingerboard with 24 frets, and Bill Lawrence L-8 humbucker with coil-tap, this guitar delivered pro-level specs at the height of the shred era. The Steinberger KB-X tremolo system's whammy bar is broken off inside the insert (noted and priced accordingly), but the guitar remains fully functional otherwise. Original hardshell case included. For collectors documenting Gibson's experimental years or players seeking distinctive '80s Gibson flavor, this is a rare find.

Solid Honduran mahogany body with beveled edges and nitrocellulose lacquer finish. One-piece quartersawn Honduran mahogany neck with graphite reinforcement and slim taper profile (.800"/.875") provides fast, stable playing. Ebony fingerboard with 12" radius, mother-of-pearl split diamond inlays, and 24 frets supports upper-register work. Set-neck construction with '61-style heel joins body at 22nd fret. Large Open Book headstock with resin-impregnated fiberboard veneer features inlaid mother-of-pearl Gibson logo (squared font style indicating early-mid 1988 production) and crown.

Single Bill Lawrence L-8 bridge humbucker with AlNiCo V magnet delivers approximately 13k ohms DC resistance—hot output perfect for hard rock and metal applications. Push/push coil tap provides single-coil voicing options. Simple 1 volume, 1 tone control layout keeps operation intuitive.

Issue: Steinberger KB-X tremolo whammy bar broken off inside insert. Guitar remains playable; tremolo functional without bar. Repair/replacement possible through qualified tech.

Working: Electronics fully functional, hardware intact (Grover Rotomatic 14:1 tuners, locking nut, roller saddles), original hardshell case included.
