yeah napattak shut the hell up, we got no place for dickheads like you here. metallica have been bought out, not sold out, and anyone who thinks ootherwise has no idea about what actualy happens. A b-bender is a device which sits in the body of the guitar, and when used it bends the b-string up a whole tone. it is usualy activated by a lever on the strap, so that you push down onthe neck and the b-string bends. they are very expensive, only look at one if your serios about country/blues playing
