Martin Retro Monel 12-String Acoustic Guitar Strings

Martin Retro Monel 12-string guitar strings were first developed in the 1930s and deliver a mellow yet crisp tone that showcases tonewoods.

Retros are the original Nickel acoustic string all the way from the 1930s. Retro strings offer a uniquely mellow, yet crisp sound that allows your guitar's natural tonewoods to be heard. They are crafted with Monel, a solid nickel/copper wrap wire - not nickel-plated - meaning there is no chance for defects in the plating to allow for corrosion. Martin's proprietary wrap wire is naturally corrosion resistant and it is incredibly strong. We also employ a sophisticated winding process that controls the coupling between the core and wrap wire to maximize intonation.

I have used the Martin Retro Monel strings on my vintage Martin 000-M, my USA made Martin DX1 Dreadnought, and I anticipate that they will deliver the same excellent tone after I install them on my brand new Martin 12 string that coincidentally I brought from here.They seem to sound best on mahogany body guitars.
Round core as opposed to hex core strings.Martin Guitar dot com illustrates the difference in the installation technique that optimizes keeping these strings in tune.Not difficult just different from using hex core strings. If you’re a fan of the acoustic tones from the 70’s and prior then you’ll probably like these strings.
Great strings.
Ease of Use
Just start playing.
Yes. They’re made by Martin.
Yes. You can spend more on strings but why?Not coated but they tend to deliver a longer life span than most strings.
