Bass of the Week: Rob Allen MB-2

Rob Allen MB-2 Bass

The Rob Allen MB-2 is a unique semi-hollow bass designed to combine the warmth of an upright with the punch of a solid body electric bass. Though it’s available in a fretted version, the MB-2 comes standard as fretless to keep with the organic feel.

The bass is offered in three variations depending on the top selected: Maple, Walnut, or Koa.

Allen matches the maple top with a mahogany body and cocobolo fingerboard, while the walnut top sports an ash body with ebony fingerboard and the Koa top is paired with a mahogany body, ebony fingerboard, and tortoise binding. The basses are given minimal oil finishes, which the luthier explains is to retain optimum resonance.

Other features include Hipshot tuners, a Fishman Matrix piezo pickup, and an optional f-hole in the body.

Available in 4 or 5-string models, the Rob Allen MB-2 is built to order with prices starting at $2800. For more info, check out Rob Allen’s website.
