RG2570 set-up

[chris_engl]

Hello everyone, i have a 2007 RG2570 (w/edge pro) and i changed the string tension from standard 9-42 to 10-46 (both DM blue-steel). Since now i never changed the standard set-up but now with the 10-46 i hear buzz from the low e string from 3/4 to 14th fret and a little from the other strings but always in the middle of the neck. I also keep my guitar in a cold place so, maybe i have a back-bowed neck but i can´t see it bowed, it looks straight to me. Anyways, if i have to move the tross-rod or anything else, please tell me how cos i never did it. Also if there is another thread explaining this tell me, i´m new in this (writing in forums)

Thanks.

Before you worry about the neck, have you made any adjustments to the bridge whatsoever? Assuming you haven't and you just threw a set of 10's onto it, the issue is at the bridge. The increase in string tension is causing a change in the float of the bridge, and forcing it to pull up from the body. If I'm correct in this assumption and that's the case, you're gonna wanna adjust the screws on the spring claw until the bridge is parallel with the body, or somewhere in that general vicinity where you feel comfortable. Tighten the screws a turn or two, and retune the guitar to check your work. Inversely, if the bridge didn't have enough tension on it, and seemed to sink into the body, loosing the screws would raise the bridge.

If I'm wrong, and you did compensate at the bridge for the added tension, but you think your neck doesn't need an adjustment, your only option is to raise your bridge up enough to kill the buzz.

If you do decide to adjust your truss rod, it's easy. It isn't this make-or-break type deal that people make it out to be, and you aren't putting your guitar in any danger doing so unless you get trigger happy and start tightening or loosening it like crazy. With that said, I really doubt that the neck is your issue right now. If you had some back bow going on, you'd be buzzing in the first 2 positions, not in the middle of the neck. However, if you're convinced the neck is your issue, tighten the rod to straighten the neck, loosen it to add more relief. Make adjustments in 1/4 turns, re-tune the guitar, and check your work.

Thank you for answering. I did all the string-changing parts: paralleling the bridge, saddles-oiling, intonation... all that appears in the manual but your right: if its back bowed the frets should buzz on the lower and upper frets but when i see the neck, if not straight, its maybe a little back bowed, and that is biased because that happens when you move from 9-42 to 10-46 i guess, so i´m really lost. All i can tell you is that the critical buzzing comes from the 7-10th fret, and compared to my Yamaha pacifica 1230, the action is higher and the 1230 don´t buzz at all .
PS: no matter what all I can do is raising the bridge or losing the neck?
I´ll post photos if I can. Thank you again.
