Featuring Revolutionary Tone Pin Saddle Design Strings Straight Through Tone Pin By removing the "kink" from the string, you harness more vibrational energy into the string giving you increased dynamics and longer, piano-like sustain. Lateral Height Adjustments Side to side adjustments of the collar allow the saddle to raise and lower while still retaining full contact with the bridge plate. This allows string vibration to maintain a connection to the body of the instrument as opposed to traditional height adjustment screws. Easy Intonation Adjustments Making precise intonation adjustments has never been easier. Using the included tool or a small Allen wrench, left to right motion will smoothly bring the saddle back and forth.
