Q: I just got an Ibanez Gio and when I tune it down to drop b, it doesn’t stay in tune. I don’t know if its the neck or the whammy bar part.
A: There are several factors here. B is a low tuning. You may need a baritone guitar to get your intonation correct on the neck. If it is a 7 string, you should be fine. Take your guitar into a shop and have it set up properly. Trem bridges are difficult to learn to reset. That being said, you may need more string tension in back if the bridge is popping up too far. Different gauge strings and tunings require different amounts of tension. The trick is to figure out how much you need. Get it in tune without locking the nut down. Once you get the bridge “set” then lock it down and you will be good. Also make sure you use a good gauge string. In B you probably want a 56-12 gauge set or thicker depending on preference.
