There are two adjustment screws on the ends of the bridge that you can turn to angle the bridge left or right. If all of your strings are sharp or flat, you can try to adjust the bridge position to improve intonation. But you may find that it's close to impossible to achieve good intonation across each string.
What are the screws on a guitar bridge for?
Different bridges have different methods for this. For example, in one common mechanism (used on Fender Stratocasters and Telecasters), screws at the back of the bridge determine the saddle front-to-back position. ... To correct a string that frets flat, turn the screw counter-clockwise to move the saddle toward the nut.
How do you adjust a bridge screw?
Use your screwdriver or Allen wrench to turn the saddle screw a fraction of an inch counter clockwise. Tune the string and check the harmonic. Keep adjusting fractionally until you have it right in tune. Different makes and models have different bridge and saddle arrangements.
