which the condition of nut and bridge saddles, the condition of strings and tuning gears,
and how strings are mounted.
As a guitar repairer and builder I noticed that often musicians suffering of tuning problems simply don't mount
the strings properly.
Here is a video which explains how to correctly mount strings on a fixed bridge guitar. This may seem a known and simple task but I am sure you will discover

Following these simple instructions will dramatically improve your tuning and playing.
