Peterson P3 Clip-on pick-up.
Eliminate noise interference when tuning with any free standing tuner such as Korg CA1 by using a pick-up. The male end plugs into electronic tuner port. Has extra long heavy duty cord. Jaws feature padded ends to clip on the instrument. The best place to clamp onto our instruments are: tuning peg of mountain dulcimer, top of bridge of hammered dulcimer, pointed top or the bridge of bowed psaltery, and a tuning pin on lap harp.
