The Martin MM13 Retro Monel acoustic guitar strings, in medium / light gauge 13-56, are made from a nickel-based alloy blend to create a quickly mellowing string for vintage tones.
These strings will bring out unique woody tones from your acoustic that you've not heard before! If you like that old-school, vintage characteristic then these are the strings for you!
In light gauge 13-56 these string a powerful bass end with a loud tone and great resonance. Great for both standard tuning when playing chords and excellent for down tuning or alternate tunings.
Also amazing for slide playing. Overall great sounding strings. The individual string thicknesses are: 13, 17, 24, 32, 42, 56.
"I play Retros for the robust tone and great durability of Monel. These are my personal string gauges, suitable for standard and altered tunings." - Laurence Juber.
