The S621QM is an S series solid body electric guitar introduced by Ibanez in mid 2015. It is made in Indonesia.

The S621QM features a mahogany body with a quilted maple top bolted to a maple Wizard III neck with a 24-fret rosewood fingerboard with offset dot position markers. Components include dual Ibanez Quantum humbucking pickups and a fixed bridge.

For 2018 the rosewood fretboard was replaced by jatoba. For 2019 the mahogany body was replaced with meranti. For 2020 the bridge was changed to the F106. For 2021 the fretboard was reverted to rosewood.

The S521 is a similar model which lacks the exotic quilted top.
