Hey guys! I got my first floyd guitar today....and Ibanez RG520.....quick question.... When I use the trem, and let go, it seems as if the trem is not going back to standard position.....my entire guitar goes out of tune almost evenly... Then, when I slightly pull back up on it, it will go back into tune perfectly, and stay like that until I use the trem again..... There are 4 springs in the back if that helps! Going out of tune isn't the problem here.....why isn't my trem going back to its original position?
