2002 Martin D15S

This is a 2002 Martin D-15S, a 12-fret, slot head, all-mahogany acoustic guitar. It shows play wear, includes a gigbag, and is in good condition. The "S" often denotes a 12-fret neck joint and slotted headstock.
 
This D-15S dreadnought, being all mahogany, delivers a warm, woody tone favored for blues and folk. The 12-fret design can enhance bass response. A 2002 model would have the 15 Series' satin finish.
