Is it normally the case a guitar's intonation goes out after being restring (if it has a floyd rose). If so how do you change intonation and what is the best way to test (eg the open string&12fret?)..
there are little allenhead bolts on each saddle, you loosen that bolt, and move the saddle forward or backward depending whether you are sharp or flat when you check the intonation on that string.
