I'm looking into buying a bass quad box, i only need just the quad box at the moment because i have access to a head i can borrow. can someone give me a bit of rundown as to what brands are better than others? i don't really need an awesome one, just one for the meantime, one around $400 - $500 (australian), so what brands are better value for money, or is it just a case of you get what you pay for in most brands?
