The K&K Hot Spot Single Head Small Piezo Acoustic Pickup delivers professional-grade tone in a compact design. At just 1/2" diameter and 1/32" thick, this universal transducer fits seamlessly on smaller instruments and tight spaces where standard pickups won't work. Despite its entry-level price, it offers near-linear frequency response and surprisingly strong output for its size. Includes double-sided adhesive film and self-adhesive jack clip for quick, hassle-free installation.
