Keith:
Are you only interested in a Fender? Might you be interested in a Les Paul or a PRS? Also, check out
Daion- manufactured at the Yamaki factory in Japan from around '78 - 83. Far superior to most Fenders, IMHO. Or maybe a Guild Starfire IV?
As to value, The Blue Book Value on the most similar listed Black Knife model, the Vintage Custom (Model GIS3VT-C), ranges from $1000 for 90% excellent condition to $1150 for 95% excellent + condition, to $1350 for 98% mint condition. I've seen them listed for a little more on eBay, though I don't recall if they sold for more. As you might imagine, they don't come up on eBay very often.
I'd be interested in trade, cash, or a combo.
