Graphite Sticks have some heft to them, which I liked and having a PASV-4 is a little piece of SE history. But asking $6k is mostly embarrassing for him, like a big kid that found that he can use the hose to harass the smaller kids.
While I don't recall his initial response, he was convinced that he had found THE most collectible Chapman Stick ever. If you do talk to him, be sure to remind him it's just an older Chapman Stick with a discontinued pickup.
