There are basses, and there are Thunderbirds!
There was a minty 2015 Gibson EB with the same electronics and P/UPs as the 2015 Gibson Thunderbird being sold with OHSC for $700 just a couple of weeks ago. That's where I'd be heading if you want a more traditional bass shape with the power of a TBird. Used expect to pay around $800.
+1 on Larry's suggestion, although slightly over OP's budget...
