I picked up a my fourth PRS recently, a Zach Meyer. Love everything about it except it seems to be hard to get it INTO tune. I'm guessing that maybe this is because the tuners have a low ratio and I overshoot? Compared to my USA Custom 24, my Torero and my EG2, the tuning on the Zack just isn't as good. Should I consider replacements? I don't want to modify the wood in any way. Advice?
