Using four carefully selected and placed piezo elements, our pickups achieve a clean, focused, natural and lush sound. The rich, full bass notes balance and blend with the clear, musical mids and high notes. It's simply the sound of the harp, only bigger. This pickup works at any volume level without feedback. Although it was originally designed specifically for Dusty Strings harps, it has since been installed with great success in a wide variety of harps built by other harp makers.
