I am looking for a good 100 Watt combo and I have come across the Fender line of bass amps. They are cheap, and from what I have heard, produce a great sound. I see that they have the Rumble 100 Watt combo and the Bassman 100 Watt combo. Is there a big difference between these two? should I buy something else besides Fender? Of course I will try them both out at the store, but I was wondering if anyone has had any first hand experience and could tell me a little more about them. Thanks in advance.
