I just bought a 1983 Ibanez roadstar II rs1600. I can't find out anything about these online. I know that only 167 of these were made and this is #140. Can anybody tell me about the quality of this thing? It plays great and the original bridge was swapped out. Thanks for looking
a pic would help. what makes you think only 167 were made? the Roadstar II series overall were pretty good guitars ( i owned 2 back in the day).
There's an Ibanez Collector's Forum that can tell you everything you want to know.

Always remember that rarity doesn't mean they're special; it may just mean they couldn't sell any of them because they weren't very popular.
