From the seller's description, it likely started out as Bahama Green. Unconventional, for sure, but ugly? Not in my book. I miss my old Bahama Green Ex-Factor (sold in the '90s to pay for a term of grad. school) a lot.
Worse than the refinish, in my opinion, are the mods to the electronics. I'm a huge nut for Steinbergers, so it's not like I have anything against EMGs (I love them in fact), but I think this Factor has been about half-wrecked. It sounds "dark"? I can make my unmodified 18v fretless Factor (34'' scale) sound dark if I want it to. I'm mighty glad I have other options, however.
The multiple re-frets suggest that, if it hasn't been entirely well-cared for, it has at least been much played in its life. So cheers to that!
