hey guys...ok i got a new ibanez rg-1550 prestige series,and well u might think i am a dufus but i have never had a locking bridge before so i dont know how to handle this problem....ok the problem is that when i tune and tighten the locking nut the tuning goes high...like from Eb to E.....i think the problem is that the bridge is raising up(towards the neck)....it has been getting higher and hence the action has been getting higher.....also i tried to loosen the strings and te bridge went low infact it went into the cavity...i dont know but is it supposed to be fixed...it is the new edge pro bridge........what do i do......and how i am i suposed to adjust the action and the bridge and all that.....but first and foremosyt what could the porblem be and how can i fix it...i appreciate any help.....thanks....
