Watch the Bends & Vibrato online guitar lesson by Jeff McErlain from Beginner Blues-Rock Soloing
Please pay extra attention to this section, as I'll show you the proper technique to both bend and vibrato the strings. These techniques play a huge role in playing in tune, as you can imagine. There's a lot of tension on the string, so to bend it requires a fair amount of force. The proper hand position and support can make or break this technique. So please, check this out repeatedly!
