JBM27 Red copyright sprite

The JBM27 is a seven-string solid body electric guitar introduced by Ibanez in 2016. It is a Signature guitar of Jake Bowen of the American progressive metal band Periphery. The JBM27 is made in Indonesia and is based on the RGA series.

It was introduced as a seven-string variant of the JBM20 which is a mass-market version of Bowen's Prestige JBM100.

The JBM27 features a mahogany body with a maple top bolted to a maple neck with a reversed headstock and a 24-fret rosewood fingerboard with binding and a special moon inlay at the 12th fret. Components include dual DiMarzio custom humbucking pickups, an Edge Zero II double locking tremolo bridge, a locking nut and locking Gotoh tuning machines.

For 2018 the rosewood fretboard was replaced with jatoba. For 2019 the mahogany body was replaced by nyatoh.
