If you spend anytime at all listening to Telecaster players, you're likely to hear some pretty crazy string bending going on. Players like Will Ray, Forrest Lee, Jr., Jerry Donahue and Jim Campilongo just to name a few. Usually this is standard stuff for country players. You can either use your fingers to do the bending; even behind the nut bends, or use a crazy device featured in this video: Fender Classic Vibe with G Bender.
This is once again, another headless demo.
And also, as a reminder, I'm not a country player, but I play one on the internet.
