I have the (stock reliced) 70s Tuners on my Nate Mendel P bass, and I have some slight OCD issue. That is that the string doesn't wind as neatly over the tuning machine as with the more modern tuners. The string doesn't form like a smooth wrap, but is more or less all over the tuning machine (hope that makes sense). My feeling is that the middle part of the tuning machine is not much smaller than the rest of the tuner, so the string isn't pushed together as much as with modern tuners. I have 3 questions: 1) Am I putting my strings on the wrong way? Or is this common with the 70's style tuners? 2) What are the possible replacements for the 70s tuners? I can't find the hole diameter anywhere.. and 3) Will the replacement be an improvement over the 70s tuners? In either weight or tuning stability (and obviously, cure my OCD so that the silk part of the string will wrap nice and tight around the machine) I have no real issues with the current tuning stability. It's not the best ever, but fair enough.
