When i received this guitar the first time, the head was broken off, but was surprisingly fast replaced with at new one. The guitar has an enormous amount of output, and you can pretty easily create some sweet feedback, although that can also be one of the guitars downside, if crank the PA up and put some distortion on it, i WILL feedback if you do not lay your hand on the strings. That being said it's a metal machine and it really works over something like Metallica, Anthrax any of the thrash bands really.
