What's a TS-9 worth - an older one

I have a friend who is looking to sell his TS-9 that he purchased in 1978 or 1979. It's a MIJ TS-9 that is in very good condition.

I believe the first year for TS-9s was late 1981 early 1982. Just check Ebay for going rates. Depends on condition and the prevailing winds :)

I was at the SC Guitar Show this past weekend and a dealer had a 1982 TS-9 and was selling it for $250.

but I wouldn't be the buyer. Mine's an early TS-9 and
has not been used since the day "The Brown Truck"
delivered my Sparkle Drive which is basically a TS-808
with a Clean Boost. Actually I dig the "Potato Bug" TS-5
a lot more than the "9".
Aside from the original "808" the "Bug Line" are my favorite Ibanez'zzzz :roll:
If You look around You should be able to get the entire
Bug Fleet for under a c-note, less even.

After doing some research it's a black label from 1982
