Just got a les paul modern this week and realized that the tuner posts are staggered (shorter posts on EAD strings). The shop said it's a new design to prevent strings from popping out from the nut and buzzing. I have walked around some instrument shops, checked some les pauls including the same model but did not find anything like this. I would like to know if this is legit? Or could there be a problem from the manufacturing process?
