Sigma GBCE3SB Grand OM Electro Acoustic Sunburst

The Sigma GBCE-3-SB Electro Acoustic is a brand new addition for 2018 that features a grand OM-14 fret body with comfortable cutaway profile, quality Fishman Flex Plus electronics, bone nut, and a performance-ready appearance, perfect for the gigging guitarist and singer/songwriter. With a solid European Alpine spruce and blackwood construction, the Sigma GBCE-3-SB produces a distinct, versatile, clear and powerful sound blended with a rich, resonant warmth and a superb response. In addition, the Sigma GBCE-3-SB features a bone nut, which adds further amounts of resonance and sustain to the guitar's overall sound. Furthermore, the Sigma's grand OM-14 fret cutaway body is similar in size to auditorium guitars, providing an idyllic multi-purpose guitar with easy access to upper frets. Lastly, equipped with a responsive Fishman Flex Plus system the player can tweak their amplified tone with elegantly-designed control knobs for a precise and smooth amplified performance.

Solid European Alpine Spruce & Blackwood Construction

The Sigma GBCE-3-SB features a solid European Alpine spruce top, providing the player with a versatile, clear and powerful sound. Alpine spruce produces more 'ringing' tones than other spruce varieties, resulting in a bell-like sound with an abundance of overtones. The versatility on offer allows the GBCE-3-SB to respond superbly to a wide range of playing styles with ease. In addition, the solid top is attached to blackwood back and sides that not only offer a stunning visual, but projects a unique tone with a balanced tonal output, top-end shimmer and the richness found in rosewood. Its blackwood body also adds warmth and resonance to the guitar's overall tone whilst closely resembling mahogany within the mid-range. Furthermore, the combination of tonewoods provides the player with a versatile instrument particularly well-suited to a variety of picking styles but will also accommodate medium strength strumming.

Grand OM-14 Fret Cutaway Body

The Sigma GBCE-3-SB features a grand OM-14 fret cutaway body, which is similar in size and proportion to grand auditorium guitars, providing a versatile instrument, well suited to a wide range of genres and playing styles. With a grand OM-14 fret body combined with its mixture of tonewoods, the Sigma GBCE-3-SB produces a full low-end, emphasis within the mid-range, and sparkles within the trebles. Its versatility makes the GBCE-3-SB able to handle both lighter fingerpicking styles to a variety of strumming patterns with ease, perfect for adding a range of dynamics to a player's individual musical style. Furthermore, the grand OM body also offers a comfortable playing experience due to its curvaceous shape and nipped in waist, providing comfort throughout both seated and standing performances. For added comfort, the GBCE-3-SB has a venetian cutaway profile, offering easy access to upper frets and more challenging chords.

Equipped with Fishman Flex Plus

The Sigma GBCE-3-SB comes equipped a Fishman Flex Plus system, perfect for the performing musician. Its elegantly designed Fishman Flex Plus system features highly detailed and stylized knobs that have been designed with ergonomics in mind. Additionally, the Flex Plus also features volume, bass, and treble controls for a precise, smooth performance. With this, the player is able to shape their amplified sound to personal preference with ease, perfect for live, studio and rehearsal settings.

Mahogany Neck & Micarta Fingerboard

Constructed from mahogany, the Sigma's neck offers a quick and dynamic response to numerous techniques while adding further amounts of resonant-warmth. Additionally, the neck has a low profile for added comfort and a better grip in each position up and down the neck. Furthermore, the neck is topped with a micarta fingerboard which offers a smooth playing experience whilst adding sonically pleasing tones to the guitar's overall sound. For added aesthetic appeal, the fingerboard is graced with unique mother of pearl inlays, adding elegance to its stylish look.

Bone Nut

The GBCE-3-SB features a bone nut, which offers excellent resonance and sustain, along with an authentic appearance. A bone nut also delivers a very balanced tone, and will last a long time. In addition, this type of nut naturally self lubricates and helps you stay in tune for longer.
