This non-locking tremolo is set on the Excalibur Supra and Special for guitarist that are looking for a rich, crunchy sound. Usually, the bridge’s pivot system is fitted with knives but we decided to replace them with ball bearings. Once the knives are worn, there is no way the tremolo can come back to its original position because there is friction. When this happens you will have detuning problems. Our ball bearings can turn 10,000 times per minute and so are impossible to wear. The perfect tuning stability of the Excalibur Supra and Special is also ensured through the locking machine heads that are precisely aligned with the strings and our traditional zero fret that eliminates friction at the level of the nut. Another important detail, is the short distance between the bridge saddle and the place where the string is anchored. Each saddle can be locked into position once intonation is set and a small roller is located at the string break point to minimize friction. The 2010 tremolo has as much tuning stability as most guitars equipped with a regular Floyd Rose.
