DiMarzio are well-known for their electric guitar pickups. But acoustic players need to get loud too sometimes The Angel Active pickup is the result of DiMarzio's mission to create an acoustic pickup that both sounds and feels great. It uses a rare earth magnetic element to fully capture the dynamics of your playing, from lightly picked notes to heavy strumming. The active electronics are contained in the endpin jack, while the volume control is mounted in the soundhole. The Angel installs easily into guitars with a 3.5" or larger sound hole.
