Philly or someone will be yer man - but yeh, I remember we had to dick about filling the holes in a Squier years ago so that I could put slotted tuners in.
When you've figured out how to use them, slotted tuners (imho, of course :lol:) beat the holy-cr@p out anything else - they don't slip, they're fast to change, even faster to take off, and they look SO tidy :D
