I have a Ernie Ball Stingray 5 bass that i bought years back and I have loved it ever since. I'm not sure how much it is worth now so if anyone can help out. The serial number for it is E13392. It's in very good condition.
For value, I would check out ebay and also the for sale thread here in this forum. I f you go to the guitar center website for used, they go for anywhere between 800 and 1100. Of course they only pay half that, but why would they buy unless they could make money on the deal.
