High-output, stick-on passive piezo pickup! By attaching the approximately 3.5cm housing to the body, it is possible to output a volume that is hard to believe is from a passive pickup. The end of the included approximately 3m cable is designed to be inserted like a shield, so there is no need to prepare a separate shielded cable. This high-performance pickup can be installed on any instrument as long as there is a 3.5cm diameter space near the bridge of the top wood. It's a recommended aftermarket pickup for those who want to play live but don't want to modify their instrument! *Due to the high output, there may be some noise when touching the main body or body during installation. Thank you for your understanding. Accessories: 2.5mm mini-pin, 1/4 inch phone cable (approx. 3m), adhesive tape
