Product Reviews for D'Addario/Planet Waves O-Port White Large (fits 3.875" - 4"), PW-OPWHL
D'Addario/Planet Waves O-Port White Large (fits 3.875" - 4"), PW-OPWHLTom DAugust 1, 2011I installed an O-Port on my Martin D-1 ('95). It has made a distinct difference in both the clarity of the individual notes and the tone of the sustain. It is slightly muddy strumming hard rock chords, but that is the only negative point I've encountered. I bought two, the other one is going in my vintage Framus Western 12-String.
