Strings are too tight and sound muffled on Lo Pro Edge
First post here. I have a 1998 RG 7620 with a Lo Pro Edge unit. I did some setup on this guitar yesterday, the action, intonation, angle of the bridge and truss rod all seemed fine.
There is only one problem, the string felt really really tight, I can't even fully bend a full step up. Also, the low B string sounded really muffled/muted, like a very old string would, but the string was brand new and fresh out of the box. If it is any relevant, the previous owner set it up in ADGCFAD (full step down) tuning, while I set it up in drop A tuning. The string gauges I used was 10-13-17-26-36-46-56. I also tried adjusting string claw screws to balance the tension.
I use three springs in the back, as well as a Tremol-No unit.
