Guild B-140E Acoustic Bass
The Guild B-140E Natural is a professional-grade acoustic bass guitar featuring an all-solid wood construction and a large jumbo body design. Designed for high-volume acoustic projection and reliable amplified performance, it incorporates a Fishman electronics system and premium tonewoods.

Overview and Construction
The Guild B-140E is situated within the brand's Westerly Collection, a series that pays homage to Guild's historic production era in Rhode Island. This model is defined by its all-solid tonewood construction, utilizing a solid Sitka spruce top paired with solid African mahogany for the back and sides.
The instrument is built on a jumbo body platform, which is traditionally the preferred choice for acoustic basses due to the air volume required to produce audible low-frequency notes. The aesthetic is understated yet premium, featuring a natural finish and a mother-of-pearl rosette.
Playability and Hardware
The B-140E is designed with a familiar 'C' shaped mahogany neck, providing a profile that accommodates various hand sizes and playing styles. It features a standard 34-inch scale length, ensuring string tension remains consistent with most electric bass guitars.
The fingerboard and bridge are crafted from rosewood, a classic choice for durability and warmth. To facilitate easy transport and protection, the instrument is supplied with a dedicated Guild gig bag.

Electronics and Sound Character
Acoustically, the B-140E is engineered for strong projection. The combination of spruce and mahogany results in a full, resonant voice with significant natural character and a pronounced low-end response. This makes it suitable for unplugged rehearsals where smaller-bodied basses might struggle to be heard.
For live performance or recording, the guitar is equipped with the Guild/Fishman BT-1 pickup system. This system includes soundhole-mounted volume and tone controls, allowing the player to make discreet adjustments without altering the instrument's side-wood integrity.
Intended Application
The B-140E is a versatile tool for bassists who work across both acoustic and amplified environments. It is particularly well-suited for:
- Acoustic ensembles: Where natural volume and unplugged presence are required.
- Practice sessions: Allowing for full-scale practice without the need for an external amplifier.
- Studio recording: Offering a resonant, woody alternative to the standard electric bass tone.
