Guitar

Tuning

• If you have a vibrato and just need to change a single string, it's better to put something under the vibrato (metal plate) so that its position won't move.
• If you need to change all strings or for some reason the vibrato changed position, you will need to change the tension of the springs. They are on the other side of the guitar. A correct vibrato position is aligned with the guitar itself (neither too low nor too high). Very good instructions are available here.
• The bridge nuts have a given direction. See this page for a visual images that will indicate you how to proceed.
