heh, other than the look is good, that twang bar there will always hinder the adjusment of the tone/volume knob actually.
To fit the tremolo aint a big problem(at least 2 holes need to be drill if using the longer type of tremolo instead of the horseshoe kinda). But to setup and intonate the instrument after that can be a hassle. I tried it on a epi g 400. And actually regret after doing so. But then, the look was quite nice and other than that, more cons than pros....
