Not so much incorrect information as an overly douchey sales person. I was in a GC south of Denver to try out the JVM410 when it first came out. The sales guy asked me what guitar I wanted and I said it didn't really matter...anything with a humbucker and a Floyd would do. He goes and grabs a new white Jem and I proceed to tune it up and test the amp. He interupts after a few minutes and says "so do you want the guitar?". I reminded him that I was checking out the amp and not the guitar and proceeded to play some more. Maybe a minute later he says "you sound great playing that guitar, should I wrap it up?".
Now I'm getting a bit annoyed and ask him why he keeps pushing the guitar on me and if it's got some kind of spiff on it or something. He laughs sheepishly and walks away. Not more than two minutes go by and he's back, once again asking if I want the guitar. I reply "Yeah, here, hold on to it for a second", hand it to him, and walked out. WTF???
