i've seen one bass player own one (left handed version) But man the dude couldn't play for scrap! So tone wise i couldn't get a good grasp on it. So i tried one myself. Verdict: it has it's moments. I own an epiphone goth bird & as much as i hate the string spacing on the goth, i didn't much like the body shape of the schecter sixx. IF he wanted a bird of different caliber, why not go back to spector? I liked that tone the best along with his early Too fast for love tones.
Formaly just replacing the stock controls on his birds with simple kill switches, now he's leaving the circuit & just adding one? Plus i'm not a fan of EMG pickups, nor do i find it necessary to have 24 frets. (at least not for my music purpose). & if i want something nikki sixx, i'll get an actual thunderbird, not this.
