The Tonewings Max Control HDC XL drum tone enhancer 4-pack delivers the added mass and reduced sustain of the Max Control HDC design in an extended-length format for wider lug spacing. Constructed from 3.2 mm bell brass alloy, the XL version accommodates lug spacing up to 3.5" apart, making it suitable for many metal drums and applications where the standard HDC model may not fit. Each 4-pack provides enough Tonewings for one drum and installs using the drum's existing hardware, offering a non-permanent way to tighten response, control sustain and achieve a more focused sound without modifying the shell.
