Beautiful craftsmanship

The finish on this Sigma is flawless. You can tell the attention to detail in the binding and fret work. It feels substantial in the hands but isn't too heavy for long practice sessions.

Incredible value for solid wood

I was skeptical about the price point, but this guitar punches way above its weight. The solid spruce top gives it a rich, open tone that only gets better with time. Perfect for strumming folk songs.

Solid upgrade from laminate

Coming from a laminated guitar, the difference in resonance is night and day. The sustain is impressive. Only giving 4 stars because the included gig bag is a bit thin, but the guitar itself is a 5.

Great sound, minor setup needed

The tone is warm and balanced right out of the box. I did have to lower the action slightly at the bridge for my playing style, but once set up, it plays like a dream. Highly recommended for intermediate players.

Best gigging guitar in this range

The built-in preamp is surprisingly clear and handles stage volume without feedback issues. The mahogany back and sides provide a nice mid-range punch that cuts through a mix perfectly.

Perfect for fingerstyle and strumming

This guitar is incredibly versatile. It responds well to light fingerpicking but also has enough volume and headroom for aggressive strumming. The neck profile is very comfortable.

5 FAQ

Q: Are these guitars made in Japan or China?

A: While Sigma originated as a Japanese brand, the current ST Series all-solid-wood models are meticulously crafted in our partner facility in Asia under strict quality control standards derived from Japanese lutherie traditions.

Q: Is the nut width suitable for players with larger hands?

A: Yes, with a nut width of 43mm (1.69 inches), this guitar offers a comfortable spacing for chord shapes and fingerstyle playing, accommodating various hand sizes effectively.

Q: Can I return this if the action is too high for me?

A: Absolutely. We offer a 30-day return policy. However, we recommend contacting our support team first, as minor truss rod or saddle adjustments can often optimize the action to your preference.

Q: What type of batteries does the preamp require?

A: The onboard ST Series preamp and tuner system operates on a standard 9V battery, which is included with the guitar upon purchase.

Q: Does this model come with a hard case or a soft gig bag?

A: The Sigma ST Series SDM-STE+ comes equipped with a high-quality padded gig bag for protection and portability. A hard case can be purchased separately if needed.
