Hello, Jon.
Someone else may have other ideas, but you asked ? so here are mine.
I'd say the range is between $3,500 and $4,500 (give or take a couple of hundred depending on your situation and the buyer's wants and desires.)
If you want to sell it quickly, price it at about $3,500 and I'll bet it will go soon. Price it at $4,500 and you may have it for a while, but who knows? It may be just what folks are looking to purchase.
It seems the short and medium scale basses are highly popular and even more desirable (to some) that the LSB. I, myself, like the big basses. Yours is very nice.
Good luck. HOpes this helps.
If I am too far off the mark I will imagine that someone will 'chime' in and let us know.
