The Shadow EBP Set is a high quality undersaddle pickup with an active endpin preamp, for steel and nylon string guitars. The undersaddle pickup will fit a standard (3/32", 2.3mm) saddle slot and has a solderless connector that plugs directly into the preamp. The endpin preamp turns on or off automatically when a cable is inserted or removed, to conserve battery power. Includes prewired battery holder with hook-and-loop attachment. Made in Germany.
