I've been playing a Milestone IV since I started playing bass. I think it's about time for a new bass, but I'm fairly low on funds. I have loved the peaveys I have played so I'm looking for a used US peavey. I have heard great things about the Milleniums, and I know plenty about them, but I'm also interested in the others, like the Forums, Forum AXs, Dyna-Bass, TL's, and Foundations. Its pretty hard to find these basses to demo, so just tell me anything you know about the differences between these basses, what they sound like, and how their slap tone is. Much thanks.
