A musical instrument slide for a stringed instrument and a method of manufacturing the same includes a slide body defining an outer wall, the outer wall configured to affect sound produced by the instrument when applied to one or more strings of the instrument. The slide includes an insert within the slide body defining an inner wall and creating a space between the slide body and the insert and further includes liquid within the space between the slide body and the insert to further affect the sound produced by the instrument when the outer wall is applied to the strings. A removable collar may be included with an aperture or opening that may vary in size to accommodate multiple users. Liquid may be selectively sealed between the slide body and the insert and be changed as required.
