What would happen if Gibson were to take the Firebird components and put them on a traditional shaped bass? How about this Gibson IV from 1987...
These are pretty cool basses, complete with Thunderbird pickups, and this one looks to be in very good condition being that it is 25 years old. Hard case is included, though not sure if it is original (I am pretty sure the original case was a rectangular wood case. This is at the Cockeysville, MD MGR store for $1200 plus shipping. Is it a super deal, probably not, but not bad for a Gibson of that age. I think they only made these in black, red, white and natural gloss, and this one is one of the nicest ones I have seen (though only in pictures, haven't seen it in person.)
