The Meinl Pickup Cajon is equipped with the DST pickup microphone and the A1.2 preamp system with volume control from B-Band. This active system includes a specially designed preamp, high-quality 1/4" output jack, and a durable battery. The structure is light in mass, adding very little weight to the instrument. The sound reproduction is amazingly pure and clear. This installed microphone system provides comfortable and easy handling in live situations without the hassle of rigging up external mics. Internal, adjustable snare wires add a range of colors to the cajon's sound. Plug in and play.
