I am going to stay with my RB110 and not purchase the RB210. The RB110's tone and size are perfect. That said, I would like more power and ultra high/ultra low on occasion. Some may say look at the RB 112. There is something about the RB112's tone that does not sit well with me. Maybe it is a Jazz bass and RB112 pairing? Or Ampeg's l------o------n-----g history of excelling with 10 inch drivers that is just sits "right" for me?
Now, if Ampeg were to make an RB110 "pro version" with the ultra high/low and more power, then that would be an instant preorder purchase for me.
