Guild Westerly B-140E Acoustic Bass Guitar in Natural

The Guild Westerly B-140E Natural is a jumbo acoustic bass designed for players who want a powerful, resonant low end that still feels comfortable and familiar. With its solid Sitka spruce top, solid African mahogany back and sides and a stage-ready Guild/Fishman BT-1 pickup system, it delivers a bold, articulate acoustic bass tone that works just as well in an unplugged setting as it does through a PA.

Drawing on Guild’s iconic acoustic bass heritage, the B-140E Natural pairs classic jumbo bass punch with modern playability. A comfortable C-shaped neck, rosewood fingerboard and a 34 inch scale make it feel instantly intuitive for electric and acoustic bassists alike, while tasteful appointments like the mother-of-pearl rosette and Chesterfield headstock logo give it a timeless, vintage-inspired look.

Whether you are underpinning an acoustic duo, adding warmth to a studio track or simply enjoying the feel of a big acoustic bass at home, the B-140E Natural gives you the depth, projection and clarity you need, with the flexibility to plug in and go whenever the gig demands it.

Classic Jumbo Acoustic Bass Power

Based on Guild’s celebrated jumbo bass shape, the B-140E Natural offers impressive acoustic volume and projection. The large B jumbo body moves plenty of air, giving you a full, piano-like low end that can hold its own in an unplugged ensemble and provide a solid foundation in any mix.

All Solid Tonewoods

A solid Sitka spruce top paired with solid African mahogany back and sides gives the B-140E Natural a rich, balanced voice with plenty of definition. Spruce adds clarity and dynamic range, while mahogany contributes warmth and focus, so every note feels supportive without becoming muddy.

Comfortable, Familiar Feel

The African mahogany neck with a C-shaped profile and 34 inch scale length offers a comfortable, familiar feel for most bass players. A rosewood fingerboard with a 16 inch radius and 22 frets keeps things smooth under the fingers, making it easy to move around the neck and play both melodic lines and supportive root notes with confidence.

Stage Ready Electronics

The built-in Guild/Fishman BT-1 system lets you take the B-140E Natural straight onto the stage or into the studio. Discreet soundhole-mounted volume and tone controls allow quick, intuitive adjustments without spoiling the classic look of the bass, so you can dial in your sound on the fly while keeping the instrument’s aesthetic clean and traditional.
