Most PBG dont come pre drilled, but easy fix just ask the guys here and you will get the nut to tail measurement for the scale length so intonation is right.The floating bridge causes string vibration from the body giving unwanted feedback, which can be stopped by glueing a thin layer of cork on underside..But you lose sustain, thats why Grohl swapped to fixed hardtail, increase sustain without feedback..At least that was the case on the Gibson Trini..Cant speak fir the PBG model you purchased...
