Pearl PJCP-1 Cajon Jingle Cup. The new Jingle Cup is an attachable set of cajon jingles, transforming any cajon into a jingle cajon. A 2” diameter suction cup holds the set of platinellas onto any cajon’s striking face, sympathetically sounding when the cajon is played. Available in brass or steel platinellas, the Jingle Cups are easily applied or removed using the plastic tab on the suction cup for quick timbre changes. A threaded screw through the Jingles allows you to easily loosen or tighten the jingles to control their volume. The versatile Jingle Cups can also be attached to the body of an acoustic guitar, a drum, or any instrument you strike, adding rhythm and flair to your music.
