Sorry - didn't see that, although I don't agree that it has much to do with watts, you can hear it very clearly with a 1W amplifier and a very clear speaker and not hear it with a 500w amp. In fact, probably easier to hear in headphones. But yes, you are more likely to hear it with more power everything else being equal.
It can be, I have been lucky in that the tuners in the G&L and Ibanez that I have done are quite large, plus I do it very near to the bend so it will go in ok, but it makes it harder.
Actually, it was even harder on the G&L, as that was flatwounds, and I had to do it again, as with the B string strung through the body, it was too much of a bend to get the string over the bridge and it didn't quite make the nut, so I had to take it out and put it through the back. luckily that gave me a bit more room!
