Ibanez RGRTBB21-BKF

The Ibanez RGRTBB21-BKF is an Iron Label 6-string baritone electric guitar designed for extended-range low tuning, tight articulation and modern heavy music. Its neck-through construction combines a 5-piece Maple/Walnut Wizard III Baritone neck with an Okoume wing body, providing strong sustain and smooth access across its 24-fret Ebony fretboard. The extended 712mm (28") scale length provides increased string tension, making the guitar particularly effective for low tunings while maintaining clear note definition.

The RGRTBB21-BKF features a pair of DiMarzio D Activator passive ceramic humbuckers, delivering a powerful, open response with tight low-end performance and strong harmonic detail. A simple 3-way pickup selector allows selection of the neck pickup, both pickups or the bridge pickup, while dedicated volume and tone controls provide straightforward tonal adjustment. The factory tuning is B-F#-D-A-E-B, giving the guitar a low-register foundation without requiring an excessively loose string feel.

A set of Gotoh MG-T locking machine heads provides reliable tuning stability and makes string changes quicker, while the Mono-Rail bridge individually isolates each string to help reduce unwanted vibration transfer and improve stability. The Black Flat finish, black hardware, Ebony fretboard and luminescent side dots give the guitar its distinctive Iron Label appearance. The RGRTBB21-BKF is supplied with heavy-gauge D'Addario EXL157 strings suited to its baritone scale and low tuning.
