I have an AX-50 by LTD. in originaly come with .09-.47 strings. I want to put .10-.52 strings. Do I really have to see a guitar tech to ajust my neck?

Thanks a lot

No, I don't know that particular guitar, but if it's half-seminally-partially-maybe slightly decent, it should be absolutely fine. If it's a 28 piece guitar made out of old kindling, you may have a problem.
It is a pretty decent guitar, LTD is part of ESP. For the price(250$) it is an arm of Mass destruction.
