    Product Description

    Sigma are renowned for their high-quality acoustic guitars; modestly-priced so that they're attainable for players of all budgets. The JM-SG45 is no exception to this ethos, formed from a great selection of tonewoods and providing excellent playability. Fitted with a stellar Fishman Sonitone pickup/preamp, this stunning instrument can be easily amplified for on-stage use or even recording scenarios.

    Rich Mahogany Body

    Featuring Mahogany back and sides, the Sigma JM-SG45 produces a deep and resonant sound with a beautifully warm and musical low-end. The large dreadnought body shape ensures brilliant projection — loud even when unplugged. Adorned with a Solid Sitka Spruce top, this helps to bring out some airy top-end character; giving lush chords progressions or finger-picked arpeggios all of the beautiful clarity they'd need to cut through in a mix.

    Luxurious Neck

    A low-profile Mahogany neck provides a substantial yet comfortable feel, with its rounded tonal properties merging well with the matching back and side body timbers. Fitted with a Micarta fretboard, this sleek wood offers a smooth touch under the fingers — making fretting a joy! A bone nut/saddle enhances sustain and keeps a traditional vibe.

    Fishman Sonitone System

    The Sigma JM-SG45 has been fitted with a Fishman Sonitone pickup/preamp — a premium under-saddle system which makes sure that the stunning natural sound of this instrument is translated through any speakers with great conviction. The moment you plug this guitar in, you will feel inspired by its high-fidelity sound!

    This guitar is a joy to play with a wonderful rich sound. Gorgeous to look at and the strings press down very easily. Based on the Gibson you can’t be disappointed.

    Due to undersize string holes in the bridge this guitar won't take standard size bridge pins, otherwise good guitar.

    The guitar was for my other half. He says the action is a little high & could do with a little adjustment.
