When people talk about Martin guitars, the first thing that comes to mind is their legendary tone and craftsmanship. But another key factor that shapes how a Martin sounds—and how comfortable it feels to play—is its body shape. Different shapes affect projection, resonance, comfort, and tone balance. If you’re considering a Martin, it helps to understand how the brand categorizes their models by shape. In this guide, we’ll explore Martin guitars categorized by shape, explain how each one feels and sounds, and help you decide which is best for your playing style.
