The Shadow SH SB-1 is a dual head contact sensor for upright bass and cello. The sensors attach to the face of the bridge with the included double-sided tape. No soldering required. The SB-2 is a high output pickup and will work with most amplifiers. If plugging into a mixer board or PA system, you may need a preamp or direct box, depending on the sensitivity of that system. Preamp not included.
Note: This is a vibration sensor that mounts to the surface of the bridge. The sensors are not designed to be inserted in the wing slot, or under the bridge feet. Does not require any modifications to the instrument. The jack attaches to the instrument with a self-adhesive hook-and-loop patch. We recommend mounting the jack to the tailpiece rather than to the body of the instrument.
