I try to do that to, but it usually ends with bouts of laughter...hahaha
One time I went, and there was a kid and his dad shopping for a bass. Kid was a little jerk, yelling at his dad, "No you're going to buy me this one!" as he points out a highend warwick....
So he pulls one down, plugs it in, begins to play, and the most awful buzzy playing begins to come out of that ampeg. That little kid did not deserve that bass....I think he got though.
wow theres alot of that out there. i went one time to look for my first bass and this emo chick was with her dad and she asked to play a warwick also. i was like "***!?!" cause she plays it for like 3 minustes then tells her dad "yah i like it lets get it" and when im leaving i see her loading it into her car
hahaha
