Overview

A fingerstyle or slide player who wants a mellow, vintage-flavored acoustic voice gets it from this Martin Retro set, wrapped in Monel wire. The nickel-copper blend is aimed at letting the guitar's own woods come through.

The maker says the alloy softens attack so the tonewoods are heard, and that the Monel wrap resists corrosion naturally. The set is also described as working well plugged in. The listing says coated but never names the coating, and it gives no individual gauges.

Who it's for

Players of blues, Americana and bluegrass who tune low or play slide and want a natural, softened attack. Heavy strummers chasing sparkle should choose a brighter alloy.

Performance notes

A nickel-copper alloy wrapped as Monel wire reduces pick attack, so the guitar's tonewoods are not overshadowed, according to the maker. The wrap is naturally corrosion resistant, which supports longevity. Medium gauge governs tension for down tuning and slide.
