Tunable cajón devices, including tuning and adjustment during a performance, are disclosed. In an aspect, the present disclosure provides a tunable cajón device wherein internal strings or cords under tension may be tuned via the manual manipulation of tuners accessible via a top surface of the cajón. As such, a cajón player may view tuner position and adjust the tuner from the traditional playing position. Adjustments (i.e., tuning of internal strings) may be done before, during, or after a performance.
