Our Take

Custom Light 11-52 sets are often chosen by players who find standard light strings a little stiff but don't want the thinner sound that can come with extra-light gauges.

The MA535 strikes a nice balance between comfort and tone. Chords still have plenty of body, but the reduced tension makes fingerstyle passages, bends and longer practice sessions noticeably easier on the hands. They're particularly popular with singer-songwriters and acoustic players who spend a lot of time accompanying vocals, where a responsive feel can be just as important as outright volume.

The phosphor bronze wrap delivers the warm, balanced voice most players expect from a quality acoustic string, while Martin's SP core wire gives the set a reassuringly stable feel under the fingers. They tune up quickly, hold pitch well and respond consistently to both a light touch and more aggressive strumming.

If you're currently playing 12s and occasionally wish your guitar felt a little easier to play, the MA535 is one of the first sets we'd suggest trying.
