The K&K Twin Spot Internal Pickup is a passive, dual-head piezo transducer system designed to amplify a wide range of acoustic instruments, including guitars, mandolins, bouzoukis, and more. Its compact ½-inch diameter heads allow for unobtrusive installation in hard-to-reach areas, ensuring minimal interference with the instrument's natural acoustics. The dual-head configuration provides a more balanced sound structure and a broader frequency range, capturing the full tonal spectrum of your instrument. The system is passive, requiring no batteries or onboard electronics, and delivers a high output level suitable for direct connection to amplifiers or PA systems. Installation is facilitated by a shielded internal endpin jack, which can be mounted externally without the need for soldering. The pickup heads are attached using a special double-sided adhesive film that is UV-resistant, ensuring a secure bond that withstands years of use. This design makes the Twin Spot Internal Pickup an excellent choice for musicians seeking a natural amplification solution that preserves the integrity of their instrument's tone.
