DiMarzio DP234 Black Angel Passive/Acoustic/Soundhole Pickup (Black)The Black Angel, a passive magnetic soundhole pickup, "hears" the entire range of the acoustic guitar from top to bottom, with no gaps anywhere. Its feel is just as important. The Black Angel tracks right and left hand dynamics, and responds immediately to the sound coming off the string. The Black Angel is quiet and, although it's magnetic, it doesn't sound electric there's no hum and no battery. Both coils are on a parallel axis to the strings,
