I was thinking of replacing my tuners but i dont know which ones i need cause some say 14:1 then others say 18:1

I have a epi les paul thinking of getting grove tuners again so i wont have to make new holes.

Thanks for the help guys
18:1 is the gear ratio not the size, im guessing you have grovers, i recommend you get the new locking grovers roto-grip i think they are called
