The OB-150RF is for the player who finds a flat banjo fingerboard hard work. The “RF” is Radius Fret: the rosewood fingerboard is radiused to 12 inches, curving gently across its width rather than lying dead flat. Guitar and mandolin players have had this for a century and banjo players mostly have not. Your fretting hand closes in an arc, so a curved board meets it where it already is — barre chords need less pressure, chord shapes up the neck sit more naturally, and long sessions cost your hand less. It is a comfort and playability upgrade, not a tonal one.
Nothing else changes. This is a 22-fret Orange Blossom with the same scale length, the same string spacing and the same voice as a standard OB-150 — if you already know how an OB-150 plays and sounds, this is that banjo with an easier board under your fingers.
The core is pure OB-150. A 20-hole bell brass flathead tone ring sits on an 11-inch three-ply maple rim with a one-piece cast flange, the same combination found on the most collectible pre-war Mastertones. That architecture produces the deep, focused, woody bark that defines Scruggs-era bluegrass. A maple neck with vintage-style inlays, a ZeroGlide nut, and Gold Tone planetary tuners keep it comfortable and in tune, and the satin finish keeps the neck fast under your hand.
Every OB-150RF is professionally set up at Gold Tone’s factory in Titusville, Florida before it ships, with head tension, bridge placement, action, and intonation all dialed in. A hard case is included.
