Re: xtra 09 feedneck
is it one with a clamping feedneck? if so why would you want to change it?
but if it really bothers you, try a strap wrench. if it still doesnt come off, try heating it slightly with a hair dryer or a heat gun then try it. dont use a vise grips until it's a last resort and youre very committed. if you use a vise grips it will scratch it very badly and depending on how tight it is it, may not work
