The Twin Spot is a two-head piezo transducer that can be used to amplify a wide variety of instruments, including guitars, saz, oud, bouzouki, balaleika, cello, dulcimer, bongos, and many more. Positioning the pickup heads at two spots results in a more balanced sound structure and a broader frequency range. The small heads are only 1/2 inch in diameter, allowing them to be installed unobtrusively and in hard-to-reach areas of an instrument. The pickup heads are attached with a special double-side adhesive film, which is UV resistant to ensure safe adhesion even after years of use. It is ultra-thin and enables the harmonic frequencies to completely pass through to the pickup disks. The Twin Spot EXTERNAL jack comes with a self-adhesive clamp for quick and easy placement on the instrument.
