Watch the Bending 3rds: Study 1 online guitar lesson by Jason Loughlin from Country Guitar Survival Guide: Lead Edition
Finally, bending! Let's revisit the interval of a third to dig into some classic country bends. Pretty much every country guitarist who has picked up a Tele has squeezed two notes together to emulate pedal steel licks or slide guitar. These do require some extra strength, so make sure to use multiple fingers on your fretting hand whenever possible. The key to making any bending lick sound good is playing in tune. Just take the time to listen closely to your destination notes. I found the best way to do this is to play each note fretted and sing them. Then attempt the bend.
I've split this chapter up into bending thirds as double stops and embellishing the interval with bending one note at a time. Bending double stops will have you bending diatonically, chromatically, setting up passing tones and bending thirds while holding pedal tones. In some cases you will be bending one note a half step and the other a whole step at the same time. Make sure you use the fingerings I show you and always strive for good intonation. Please check out Jerry Donahue. He's a master of this stuff. Such a great player that still doesn't get as much attention as he deserves.
