Ibanez SR370EF-BBT Fretless Bass Brown Burst Rosewood Fretboard

Ibanez SR370EF Fretless Bass
The Ibanez SR370EF brings professional features to an accessible price point, making it an excellent choice for bassists exploring the fretless world. With its 5-piece Maple/Walnut neck, Jatoba fretboard, and PowerSpan Dual Coil pickups, this bass is designed to deliver tonal clarity, dynamic expression, and effortless playability.

Its Accu-cast B120 bridge ensures rock-solid stability, while the Ibanez Custom 3-band EQ with Power Tap switch provides a wide palette of tones — from punchy single-coil articulation to warm humbucking power, and a hybrid mode for the best of both worlds. The fretless design offers smooth slides, expressive vibrato, and that signature singing tone unique to fretless basses.
