Sigma 000M-15

This describes the body size and is a direct borrow from Martin guitars, who name their different body sizes as 0, 00, 000 etc. 000 guitars are often known as Grand Auditorium models.

This is another reference to Martin guitars. The 15 series came about during the Great Depression that followed the stock market crash of 1929 in America. Mahogany was a widely available and inexpensive wood back then (unlike today) and Martin were able to make a range of quality all-Mahogany guitars that could be sold at a much more economical price than their usual Maple and Rosewood guitars. The 15 series outlasted the Depression as the instruments sounded great and looked superb. They were also quite distinctly different from what was otherwise available. These modern day Sigma guitars use the Martin 15 series as a blueprint and have therefore incorporated the '15' into their own names.

Yes you can! The Sigma 000M-15E+ is the model you want. It has a Fishman pickup system with onboard preamp to provide you with an excellent plugged in live sound.

The Sigma 000M 15 Series is a popular acoustic guitar model that is based on the old Martin 00015. The Sigma interpretation of this classic design is made with a solid mahogany top which gives it a wonderful tone.
