I've got the new Fender Modern Player Jazz V and i love everything about it except the tuners. The stock tuners on the MPJV have super-long tuning key shafts and i've already damaged one of them due to how much they stick out. They seem to add a little neck dive as they are pretty substantial in size as well. I have been doing research on what tuners i would prefer and i'm pretty much set on the Hipshot Ultralites. Now by getting those, i do understand i will have exposed holes on the back of my headstock, as they are not a direct replacement for the tuners i currently have. Would i better off having my local repair guy fill the holes or is it an easy fix i can do at home? Like a simple "fill-sand-finish" kind of thing? Or should i just go with a direct drop-in replacement tuner?
