This precision engineered nut is made with a specially formulated material which couples the strings' vibrations to the neck and brings out the hidden harmonics and richness in every note. It is based on the highly resonant TUSQ man made ivory, but is impregnated with PTFE to improve the tuning performance of the guitar. How does it work? Other nut materials have a tendency to bind the strings in their slots. When you are tuning your guitar you might hear the tell tale "ping" of the strings releasing under tension or have difficulty keeping your guitar in tune when using a tremolo or doing string bends. There are many temporary solutions to this problem, but wouldn't you rather a permanent one? Black TUSQ XL has PTFE lubrication impregnated all the way through the material (PTFE is the slipperiest substance on earth...500 times more slippery than graphite.), so you never have to worry about string binding at the nut again. Since the PTFE is impregnated right through the material, it doesn't matter if you sand or file to a different shape, it will keep on working. So go ahead and use that tremolo or do massive string bends with the confidence that you will stay in tune.How does it sound? BLACK TUSQ XL will bring out hidden harmonics in your guitar. The highly resonant material couples your strings' vibration to the neck better than anything else. You will hear more richness from every note, especially on open strings.
