Abstract: A percussion pad assembly has a beatable membrane maintained within a frame. A resilient pad may be included beneath the membrane with a lower plate or other member to trap the pad with the membrane. The tension of the membrane is adjustable by tension rods accessible from underneath, which may act upon a bearing ring positioned within the frame against the membrane. The lower plate is removable to allow access to the resilient pad for removal and/or replacement. The frame may include multiple portions that are separable to allow access to the resilient pad, bearing ring and membrane.

Abstract: An adjustable and reusable electrical assembly has an electrical unit, such as a plug unit or light unit, configured to engage with a cable. The electrical unit has a body that defines a channel connecting opposite pass-through openings. A first contact member and a second contact member are positioned with at least a portion in the body, each contact member having a piercing member. The cable is engageable with the plug unit extending through the channel with one piercing member in conductive contact with one wire and the other piercing member in conductive contact with the other wire. The cable can be disengaged from the plug unit and re-engaged at a different transverse position to change the length of the assembly.

Abstract: A telescopically adjustable board for mounting musical instrument pedals includes a first inner rail-outer rail pair. The outer rail has a tubular shape defining a hollow track and the inner rail is slidably received within the hollow track with the outer rail circumscribing the inner rail. Each of the inner rail and outer rail is configured to fixably attach to a musical effects pedal. The board may include a second inner rail-outer rail pair substantially parallel to and spaced from the first inner rail-outer rail pair. The inner rails are slidable relative to the outer rails between a fully extended position and a fully retracted position to adjust the longitudinal length of the board.
