The Eastman MDO305 Octave Mandolin expands the mandolin family with a bold, full-voiced instrument that opens new musical territory while maintaining the clarity and cut mandolins are known for. Featuring all-solid wood construction, this A-style octave mandolin pairs a responsive Sitka spruce top with resonant carved maple back and sides, delivering a rich, woody tone with extended low-end depth and ringing trebles. Whether you're backing up fiddle tunes, exploring Celtic textures, or layering in folk or acoustic pop, the MDO305 adds warmth, texture, and resonance that standard mandolins can't always reach.

The 21” scale length, longer than a standard mandolin but shorter than a guitar, strikes a comfortable balance that suits both mandolin players and guitarists venturing into octave territory. A soft V-shaped maple neck and ebony fretboard provide a smooth, stable playing surface, while the parallel bracing and Truetone satin finish allow the solid tonewoods to breathe and project. With classic appointments, reliable hardware, and a structured gig bag included, the MDO305 offers a professional-level voice at a remarkably accessible price. Available now at Haggerty’s Music.
