Sigma JM-SG45
Part of Sigma’s Golden Era spirit, The Sigma JM-SG45 draws inspiration from the legendary acoustics of the 1930s. Its warm, dark voice is full of character, with a strong focus on the mids and lows that gives chords real weight and emotion. Strummed passages ring out with long, satisfying sustain, while picked notes stay clear and expressive.
JM-SG45 is a guitar that shows exactly what Sigma has always stood for: heart, heritage, and serious value without compromise. Rooted in Sigma’s long tradition of delivering exceptional instruments at honest prices, the JM-SG45 lets the guitar do the talking.
There’s nothing flashy here, and that’s exactly the point. The craftsmanship is confident and refined, and the guitar feels instantly comfortable in your hands. It’s the kind of instrument that invites songwriting, rewards dynamics, and fills a room without trying too hard.
The JM-SG45 is proof that a great acoustic doesn’t need to be expensive to be inspiring. A guitar with soul, history, and a sound that stays with you long after the last chord fades.
Every guitar in our store is completely checked and set up by our guitar luthiers so that the guitar is easy to play yet without buzz. And if you have any special wishes regarding setup - tell us (or specify) when making an order and we will be happy to make a perfect guitar for you :)
Also, you have to keep in mind that wood is a living material. Guitar’s geometry changes a little over time, adjusting to temperature and humidity, so there is no setup that can last forever. To save you a headache, we have a free setup service for our instruments! If you feel that something is off you can bring it to us so that we can return everything to it’s perfect original state.
For online orders we manually pack each guitar into a ton of wraps and carton and also have full insurance for all our shippings. So that you wouldn’t worry that something might happen on the way.
