Earvana - Compensated Tuning Systems for Guitars

Inventor Rick Logacono and JP Cervoni explaining just how the Earvana Compensated Tuning System works. Earvana manufactures and distributes revolutionary guitar intonation technology. The patented technology is a uniquely designed nut created to improve the sound of your guitar. You have probably noticed that it is nearly impossible to tune your guitar so that the chords in the first 5 frets ring true for any open chords. Earvana has solved this problem by developing a nut that compensates for the errors that are inherent in 99% of all stringed instruments. check it out more at: www.earvana.com
