Re: PLEASE HELP: Is this the actual Bad Horsie guitar Steve used!
That's not THE bad horsie. Look at the knob configuration, as well as where the sustainer switches are placed. On the REAL bad horsie, the knobs are standard black skirt knobs, and the sustainer switches/knob are near the tone knob, and there's no silver knob on the bad horsie. Otherwise, that looks like a fairly close replica.
AND the sustainer unit is in the neck slot, not the middle slot.
EDIT: If you need more proof that the guitar isn't the bad horsie, look at the first picture on the left side, it's Vai playing MOJO, the real bad horsie (well, pre-Neville). Compare the control options on MOJO to the control options on the guitar that's shown modded.
