Re: telecaster, a metal guitar?
You can always try to fit a square peg into a round hole, but really...a Tele is the wrong guitar for the occasion. There's no two styles more opposite than country and metal, and Teles are primarily twangy country instruments. I could take some flack for that, since Teles CAN be used for anything, however, without a humbucker, the only highgain sound you'll get out of a Hotrail/Tele is hot, midrangey twang.
If I were you, I'd swap that Tele for something like a Schecter, Jackson, or other guitar that's more suitable to the style you like. Teles are easy to sell, so you could be shopping for your next guitar within a couple weeks. Just my two cents.
