We offer the slide designed by Latch Lake Music Products in collaboration with Leo Kottke, the AcoustaGlide slide, which is now available with Dynamic Diffusion Technology. It enables superior sustain and a wide controllable range of dynamics and tone. Latch Lake Music Products has taken the original design of the brass AcoustaGlide slide, transformed it to steel, then applied a special heat treat process. The end result is a lustrous black surface finish that seems to provide slide players with more “note” than ever. The AcoustaGlide slide with Dynamic Diffusion Technology is available in four sizes, each with identical length (2.507″ or 63.68 mm), wall thickness and shape, with inside diameters as follows: small 11/16″ (17.42 mm), medium 3/4″ (19.05 mm), large 13/16″ (20.64 mm) and extra-large 7/8″ (22.25 mm).
