Easy to install and works great!

Absolutely the best way to mic the harp!! I have tried multiple pick ups, and external mic placements, but this gives clearer, truer sound than ANYTHING else I've tried. It's easy to "install" and I creatively used some sticky backed Velcro on the inside of the body to secure the transducer, so no holes or external clamps required. I also purchased an adapter from Amazon so I can plug in directly to the mic cable.

This pickup delivers a clear and strong signal to your speaker. The built in pre-amp makes all the difference. The pickup attaches to the back of the soundboard via the supplied putty and can be removed easily. I have used it on my concert grand, semi-grand and smaller harps. All have worked well. You don't have to drill any holes. NOTE: I don't fiddle with all the little devices to run the wires along the side of the soundboard. Your best bet is to simple pull the battery pack through the sound hole so that all the wires are away from the soundboard. I wrap the extra wire around and attach the battery pack to the back of the harp with a discrete rubber band. You don't want those wires touching the soundboard and creating a buzz situation.

works perfectly, love it! I use it on a Heartland Harp 34 string Dreamweaver.

Everything needed to install was included, especially the clear instructions. Well designed. I previously had installed on another instrument the product of a competitor, and this proved to be superior.
