Gearmanndude rocks the Compensated Locking Nut!

"COMPENSATED locking nut reviewed on an Anderson Telecaster. If you listen to the open chords of the uncompensated you will hear an imbalance in string vibration and chord clarity. With the nut all strings will vibrate equally, thus providing compensation. This is an amazing concept and design. For over 30 years, people have struggled with the intonation issues of locking nuts and heavy hitting wang bars...these guys have cured it! The patented design keeps the usual tuning suspects in check, while maintaining sustain and a clear path to the tuning machines. The pitch shifting when switching between nuts, is my is not from the nut. Just had my tuner calibration switched and did not realize it until it came time to edit. Dig it!" - Gearmanndude

"I love the in-tune sound I get with a compensated nut. I'm so glad I'll be able to get that same intonation on my Floyd-equipped guitars."
- Alec Lee, Moderator from The Gear Page
