The Dimarzio DP130 Acoustic Model is a piezo-electric transducer that can be mounted in any location on the guitars top. A non-hardening putty is used to mount the pickup, allowing simple installation and removal.
Every acoustic guitar has its own balance of highs, mids and lows, and its easy to experiment with the position of the Acoustic Model to determine the spot that achieves the best tone for your taste. It can also be semi-permanently mounted on the inside face of the guitar and connected to an acoustic endpin jack, so its practically invisible. The Acoustic Model works on all steel, bronze, and nylon string instruments.
