Developed in close collaboration with Grammy-winning bluegrass legend Carl Jackson, the Gold Tone OB-3CJ “Ruby Pearl” is a signature-grade professional Mastertone-style banjo built to deliver authentic pre-war punch, warmth, and unmatched stage presence. Named in loving tribute to Carl’s mother, Ruby Pearl, this instrument features an exclusive custom peghead inlay centered around a genuine ruby gemstone. Paired with rich mahogany tonewoods, lustrous gold-plated hardware, a 3-ply Canadian maple rim, and our flathead tone ring, the OB-3CJ proudly takes its place at the top of our Legend Series. Every OB-3CJ is fitted with Gotoh planetary tuners, a Zero Glide nut for superior tuning stability, and is fully shop-inspected and set up at our Titusville, Florida headquarters. Deluxe hardshell case included.
