The Pickup Jack Clamp is a clean and elegant solution for anyone who is thinking about installing a pickup but is reluctant to drill a permanent hole for the jack. This easy-to-use, repositionable clamp is designed to be used in conjunction with a pickup system, such as the Dusty Strings P10 (26-30 strings) or P20 (32-40 strings) Pickup, and provides a removable way to securely hold the pickup jack in the back of the harp. It accepts a standard 1/4" jack and is adjustable to fit a wide variety of lever and pedal harps. The lower soundhole is a suggested installation location, but your harp may have internal braces or features that would accept the jack clamp just as well. The rubber padding on the inside faces of the clamp will grip any surface and hold the clamp firmly in place without harming the instrument. You can experiment to find the location that works best for you.
Note: The Jack Clamp is a pickup accessory, not an actual pickup.
