When extra amplification is needed, dial-up your cajon volume and mix your tone with the Meinl pickup cajons. The Pickup Vertical Subwoofer Bass Cajon is equipped with passive Piezo pickups for both snare and bass tone. It comes with a volume and tone knob so you can find your perfect mix. A quarter-inch cable jack allows you to send your signal through any amp or PA system (cables not included). Additionally, this cajon is equipped with a quarter-inch “link” jack where can link other Meinl passive pickup instruments through this cajon's system and control their output with the cajon's dials. This eliminates the need for additional amps or outputs to minimize your setup. Ideal for any plugged-in outdoor show, large venue or intimate acoustic coffee house set, the Meinl Pickup Vertical Subwoofer Cajon is extraordinarily versatile for any setting. Inside this cajon is a bass reflex system that directs sound waves and air through different channels before projecting out from the large, forward-facing vertical sound ports. This gives the frequencies more time to develop inside the body of the cajon, resulting in ultra-low, enhanced bass waves. Think of it as a mechanical subwoofer. Constructed with a Baltic birch frontplate and durable MDF body that produces a punchy, warm sound with depth and sensitivity. Internal fixed sets of snare wires (the same type found on snare drums) are fitted against the playing surface to produce a snare sound that complements the cajon's natural bass notes. Great for finger rolls, deep back beats or brush patterns. This extra-wide cajon measures 15 ½” W x 19 ¼” H x 11 ¾” D.
