The JSM20 is a hollow body electric guitar model introduced by Ibanez for 2018. It is a signature model for American jazz-rock guitarist John Scofield. It was initially made in China, but production moved to Indonesia in mid-2018.
The JSM20 features a thin, double cutaway, semi-hollow body design constructed of a laminated maple top with ƒ holes and multi-layer binding on laminated maple sides and back. The set-in sapele neck has a 22-fret ebony fingerboard with binding and aged white acrylic and abalone split block position markers. Components include dual Ibanez Super 58 humbucking pickups with gold covers and individual volume and tone controls and a tri-sound switch for the neck pickup, a Tune-o-matic style bridge with Quik Change III tailpiece, a bone nut and a black pickguard.
For 2019 the mahogany and maple neck was changed to nyatoh and maple; additionally, the body species was changed from maple to linden. For 2020 the bridge was changed to the new Gibraltar Artist. For 2021 the body (front, back and sides) was changed back to maple.
The JSM10 is a similar model with a flamed maple construction and a burst finish.
