Our TD-M has the understated look of a traditional mahogany guitar, but has a sound that is anything but understated. Flat-top construction, a Sitka spruce top and mahogany back and sides are standard, subtly decorated with tortoise-style binding and four-line top purfling. The TD-M combines the power of the rosewood TD-R with a warmer, more balanced tonal spectrum that may leave you breathless.
