Sigma JM-SG45+

Sold out
Original price £499.00
Current price £449.00

The Sigma JM-SG45+ features a solid sitka spruce top paired with mahogany back and sides, which produces a versatile sound of deep lows, warm mid-range, and bright singing highs. It is able to accommodate numerous genres and techniques with ease; from lighter fingerpicking styles, to heavier more aggressive strumming patterns.

Equipped with Fishman Sonitone electronics discreetly mounted within the soundhole which offer basic sound tweaking via rotary controls for tone and volume, the Sigma JM-SG45+ is an ideal instrument for the gigging guitarist, as well as being well-suited to studio environments.

Constructed from mahogany, the Sigma's neck delivers a resonant rich warmth that responds superbly to many different playing styles with equal ease. Additionally, the neck has a low profile shape for added comfort and a better grip in each position up and down the neck. 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.

The JM-SG45+ features a real bone nut, which offers excellent resonance and sustain, along with an authentic appearance. This type of nut naturally self lubricates and helps you stay in tune for longer.
