Bluegrass music is one of America's finest musical traditions. C. F. Martin & Co. has been a part of this tradition for many generations with our legendary instruments and strings. Martin Bluegrass sets combine rich, deep bass strings with bright treble strings in specially matched sets to give bluegrass musicians the sound that discerning audiences appreciate.
