I have an ESP LTD Surveyor bass with a broken tuning head (for the G string). Their is nowhere to get the original piece, but I can replace it with a Fender tuning head. It would look right (from the front) despite being very slightly bigger, but I am worried that it could possible ruin the tension/tuning/something I don't even KNOW can be ruined on my bass. Bassically (pun INTENDED) I want to know if it is safe to do it.
