DiMarzio DP136 Super Natural Plus Acoustic Pickup (Rosewood)The Super Natural Plus is just what its name implies it goes beyond ordinary sounding pickups with incredibly crisp treble and tight bass response, and patented 60 cycle hum reduction. This combination allows acoustic players to deal with real world situations where feedback and weak sound can be major problems. The pickup is encased in a plastic cover molded to look like dark rosewood, including the wood grain. It installs easily beneath the strings.
