The Mastertone® OB-3EF is built on the already great OB-3 platform, but adds extra frets for extended playing range. The OB-3EF delivers a tight, dry crack on every note with a fast response and clean separation.
The standard OB-3EF is made with a 3-ply Canadian maple rim, a mahogany neck and resonator, and a Presto tailpiece. Gotoh planetary tuners and a no-hole bell brass flat-top tone ring round out the OB-3EF's impressive feature set. A host of customization options are available to players, including different rims, tone rings, tailpieces, and more.
