I just got my new ibanez rgr320ex today. It doesnt stay in tune very well and even worse when i try to tune it my bridge keeps raising. Whats the matter/what can i do?
1. You have to stretch the strings A LOT before the guitar will hold tune for a long time.
2. What do you mean the bridge is raising? Do you have a tremolo?

My things:
Bowes SLx7
Washburn WG587
Washburn X40Pro
Washburn X50
Washburn HM24
Washburn WR150
Laguna LE200s
Arietta Acoustic
First Act
Valveking 112
VHT Deliverance

You're gonna have to adjust the springs in the back of the guitar.. should be a one time thing until you change string gauge. I'm going from 9-46 to 10-46 next time I change and am not looking forward to messing with it.
