  • $1,10999


The Sigma JM-SG45+ Acoustic-Electric Guitar is a a sloped shoulder dreadnought in sunburst finish that takes direct inspiration from the famous J-45 acoustics but with a host of modern additions and an attractive price point. 

Sigma have really captured that classic, vintage styling thanks to this models tried and tested choice of matched tonewoods. An authentic solid spruce top with mahogany back, sides and neck mean this isnt just a guitar to look at, it excells at reproducing that warm, booming tonal bliss that once were only as accesible as your pockets were deep. 

As well as tone the playability of this JMSG45 is very important, its for this reason that Sigma have selected a high quality bone 1 3/4" nut and saddle for extra stability while the shorter 24.75" scale length adds to a fast, luxurious playing experience created by the micarta fingerboard.

With this stylish retro electro-acoustic there are many small touches that really set off the look but are also a huge part of this guitars overall usability in multiple musical environments. Beautiful nickel open geared Grover tuners are provided for flawless, reliable tuning as well as an understated black pickguard to protect the finish from unwanted scratches and white binding to complete the authentic J-45 look. 

Subtly worked into this models design is an impressive Fishman Sonitone Pickup system to offer the user a choice of amplifed playing whether it is using an amplifier or a PA system, making this Sigma a must have for home, stage or studio use.
