How do you adjust the intonation on a floating bridge?
To adjust floating bridge intonation on a guitar, first check the 12th-fret harmonic and the fretted 12th-fret tuning of both E strings (high and low). If properly intonated, the fretted and harmonic 12-fret pitches of both E strings will agree, with none of them being sharp or flat.
How do you adjust a floating tremolo?
Changing the spring settings is all about the two, large screws inside the rear of the vibrato cavity. Tighten them in and you pull the springs more; loosen them and you allow the strings to pull the vibrato upward. Changing the spring's setting changes the pitch, so make the change and then re-tune!
