The JSM100 is a hollow body electric guitar model introduced by Ibanez for 2001. It is a signature model for American jazz-rock guitarist John Scofield. It is made in Japan.
The JSM100 is a faithful recreation of Scofield's trusty 1981 AS200 which had long been his primary guitar. Every aspect of that AS200 was carefully measured and faithfully recreated in the JSM100. Among the differences requested by Scofield for the JSM100 are a side-mounted output jack and elimination of the AS200's Tri-sound switch.
The JSM100 features a thin, double cutaway, semi-hollow body design with a flame maple top with ƒ holes and multi-layer binding and maple back and sides mated to a set-in mahogany neck with a 22-fret compound radius ebony fingerboard with binding and pearl/acrylic and abalone split block position markers. Components include dual Ibanez Super 58 humbucking pickups with gold covers and individual volume and tone controls, a Gotoh Tune-o-matic style bridge with Quik Change II tailpiece, a bone and brass nut, a black pickguard and Gotoh tuning machines.
For 2011 the tailpiece was switched to a Gotoh unit and the nut was changed to bone. For 2018 the wood species was changed from flame maple (top) and maple (back/sides) to figured anigre.
The JSM10 is a more affordable Chinese-made version. The JSM20th is a special anniversary version with a plain maple top with black finish and custom pickups.
