A kit for attaching one or more interchangeable accessories, for example, sound makers, fashion accessories, utility accessories, instrument accessories, etc., to an instrument, for example, a drum stick, a drum head, a post of a bass drum pedal or a hihat, a cajón, a microphone, a guitar, a stand, etc., to enhance sound, functionality, and visual elements of the instrument is provided. The kit includes one or more interchangeable accessories and at least one attachment system. The attachment system includes an attachment member and a connector element. The attachment member, for example, a clamp assembly with an accessory housing and a release assembly, or a generally cylindrical attachment member, or a cap member is removably attachable to a predetermined location of the instrument. The connector element is a female connector or a male connector for engageably connecting the attachment member to an opposing connector of one of the interchangeable accessories.

An acoustic insert for lining a loudspeaker reflex port, the insert comprising an elongate hollow tube formed of a flexible material, having an outer wall sized and configured to seat within the port and an inner wall extending in the elongate direction, the inner wall having a circumference which varies along the length of the insert, When inserted in a port, the insert alters the port resonance so as to vary the acoustic perfoi mance of the loudspeaker.

An adjustable drum mount composed of a fixed component and at least one mounting component, wherein the relative position of the mounting component with respect to the fixed component is adjustable. The fixed component is durably attached to the drum shell with fasteners. The fixed component has a planar, extending member, which connects with the mounting component(s). The planar, extending member has one end, attached continuously to the bulk of the fixed component, called the fixed end. The planar, extending member has another end, disposed distal to the fixed end, called the free end, which can vibrate. The mounting components can be mounted substantially anywhere between the fixed end and the free end. The adjustment changes the stiffness with which the drum mount connects the drum leg or support to the drum.

Provided is a stand for a musical instrument, the stand including a pole in the shape of a stick extending in one direction, and a plurality of legs extending from the pole and arranged in a circumferential direction of the pole. At least one of the plurality of legs is a rotatable leg attached to the pole so as to be capable of rotating about a central axis of the pole. At least one of the plurality of legs is an offset leg held by the pole such that a longitudinal axis of the offset leg is apart from the central axis of the pole without crossing the central axis when viewed in an axial direction of the pole.

A device integrally joined with the ported opening of a musical bass drum resonant drumhead for regulating the amount of vibrating airflow passing through the inside of a bass drumshell and continuing through the ported opening for effectively controlling undesirable higher frequency drum sounds precipitated by the airflow produced upon the striking of the batter head.

A drum cart for supporting and transporting a drum set between locations. The drum cart includes support arms, a handle, wheels and a support bracket adapted to releasably couple a bass drum to the drum cart and place the bass drum into a performance position by lying the drum cart on the ground horizontally.
