C.F. Martin & Co. is arguably the most influential acoustic guitar manufacturer in history, known globally for their invention of the definitive Dreadnought body shape and the innovative X-bracing system. A Martin acoustic guitar provides the foundational tone for folk, country, bluegrass, and Americana, with a huge, resonant voice. The Standard Series is home to legends like the rosewood-backed Martin D-28 and the mahogany-bodied Martin D-18, both industry benchmarks for powerful projection. The line includes smaller, fingerstyle-friendly bodies like the OM (Orchestra Model) and the 000 (Auditorium) series, renowned for balance and comfort. Martin offers high-value options in the Road Series and the all-solid mahogany 15 Series, alongside premium craftsmanship in the Modern Deluxe and Custom Shop lines. Played by icons from Bob Dylan and Johnny Cash to Eric Clapton and Ed Sheeran, a Martin Dreadnought or OM is an investment in a rich musical heritage and a lifetime of professional tone.
