Until the other week I've never really looked at a list of the stuff I've got/had like that. 7 electric guitars, 8 acoustic guitars, 3 basses, a uke, a mandolin, some drums and a piano! I was seriously kitted up about 3 years ago! Not that I'm not still seriously kitted up now! haha
Here's a little photo of the Hofner bass and the Richwood ES-335
