Independent shopping perspective
The Korena take
The MA550S is a medium-gauge acoustic set made with 92/8 phosphor bronze. Its silk-wrapped ball ends place a soft protective layer at the bridge end, helping reduce wear on the bridge and bridge plate as you play and when you change strings. The set is defined by its 13-17-26-35-45-56 gauge sequence, making it a direct choice for players replacing an acoustic set in that medium range.
Strong match
Who this is for
