The JBM20 is a 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 JBM20 was made in Indonesia and is based on the RGA series.

It is as a mass-market version of Bowen's original signature guitar, the Prestige JBM100.

The JBM20 features a mahogany body with a maple top bolted to a maple Wizard III neck with a 24-fret rosewood fingerboard with binding and a special crescent moon inlay at the 12th fret. Components include an Edge II double locking tremolo bridge, dual DiMarzio Titan humbucking pickups controlled by a 5-way selector, a locking nut and locking Gotoh machineheads.

Differences from the JBM100 include the bridge, neck and fingerboard wood species and tuning machines, but the body style with reversed headstock, finish and signature DiMarzio pickups are retained.

The JBM27 is a seven-string version of this guitar.

The JBM20 was discontinued after 2017.
