i had one fitted today, the guy put it on the back on the heel which really isnt a biggy, what i am worried about is does this fall in line with martins warranty? cos ill be damn gutted if i have voided it as he put it in the wrong place!

thanks guys!
on the back of the guitar, on the heel. at the base of the neck.

sorry forgot to mention that!
The issue wouldn't be where he put it, but rather if he was a Martin Authorized repairman.
