Abstract
Percussion instruments such as cajóns including auxiliary devices such as snares are disclosed. The positioning of the auxiliary device or devices with respect to the main body of the percussion instrument can be adjustable so as to produce different sounds depending upon the auxiliary device position. In one embodiment, a lever device on the back of a cajón is used. The lever device is linked to one or more snares by an adjustment rod and/or an auxiliary bar. As the lever device is adjusted, the positioning of the one or more snares and the amount of the snare wires that is in contact with the back of the tapa is adjusted, resulting in different sounds when the cajón is played.
