Review: Just try it - I've been playing for 20+ years and bought this for my son to take to school for guitar class. Was gonna go with a Yamaha but after reading the reviews for both brands I decided to go with this guitar and I'm glad I did. Was packaged perfectly, as for the guitar not to receive damage during shipment. The string height was perfect right out of the box, just tune and play. And with it's solid top and quality construction it sounds just as good as it plays. Tuners work fine and hold tune, intonation was great and I was just really surprised and impressed on the amount of quality you get for the money. I highly suggest this for a beginner or even a beat around, camp guitar for anyone regardless of experience. Sigma is a great brand and you won't be disappointed.
Review: Beyond expectations - I ordered this at a discount since the box was damaged. the guitar inside was in perfect condition. I could not find a scratch on it or anything wrong with it. The box is very heavy and kept the guitar safe despite the external damage. The guitar itself only required some tension on the truss rod to achieve a perfect low action. The guitar has a nice rich sound low E thru high E and is very clear and articulate. The tuners are very good and it stays in tune. Fit and finish is excellent in my opinion. In conclusion. the quality of the materials, the excellent fit and finish, the attention to detail, the Martin inspired design. All of this makes this guitar an outstanding value. A great choice for your first guitar or as addition to your collection.

### ⭐⭐⭐⭐⭐ Wonderful quality at a reasonable price
*by L***. on April 19, 2025*

It arrived in perfect condition. The craftsmanship is 1st rate. Finish, fretwork pickup all are excellent. It plays great without and setup work. The overall tone is well balanced, not as dark as a typical Dreadnought body but not overly bright. The electronics perform perfectly. For this price it's a definite winner. I own a Martin D18 and a Taylor 814CE. Of course they are better but cost 10 times more than this. My son enjoyed it.
