Ibanez RGRTBB21-BKF Black Flat RGRT Iron Label

Iron Label: the "no compromise" RG in the Ibanez universe

An iconic model at Ibanez, the RG series has established itself as a reference for fast playing and precision. The Iron Label variant takes this philosophy even further: a deliberately minimalist approach focused on efficiency, solidity, and electronics designed for saturated tones. The RGRTBB21-BKF fully fits into this "pure metal" lineage, with a baritone configuration and gear built to withstand the heaviest riffs.

Who is this baritone RG for?

This electric guitar is particularly suited for intermediate to expert guitarists seeking exemplary tuning stability in low tunings (drop, B standard, etc.). It excels in modern metal, djent, metalcore, prog, and all styles requiring a fast response, strong definition, and excellent note separation, even under heavy saturation.

Sound characteristics

The long 28" / 712 mm scale provides higher tension and better clarity in the low end: riffs remain tight, and attacks keep their bite. The Nyatoh wings add a dense low-midrange and warm presence, while the ebony fingerboard enhances attack and precision, ideal for fast patterns and tight palm mutes. The neck-through design promotes generous sustain and vibration continuity across the entire range. On the electronics side, the DiMarzio D Activator pickups deliver high output, fast response, and excellent definition: perfect for heavy rhythms and cutting leads. The mono-rail bridge improves string-to-string separation, and the Gotoh MG-T locking tuners enhance tuning stability.

Recommended compatible accessories

For transport and protection, the recommended case is the MR350C and the recommended gig bag is the IGB540-BK. To maintain the original feel (tension and response in low tuning), favor a set of D'Addario EXL157 strings with gauges .014/.018/.026/.044/.056/.068.
