I have a 25 watt Ibanez bass amp and i need something that i can do small gigs and band practice with. I have a peavy millenium bass and i don't plan on replacing it. I have my eye on these amps, what do you guys think about them? I have a budget of about $300-$400 (400 would be a stretch).

Ampeg BA112 50W Single 12 Bass Combo

Fender Rumble 60 Bass Combo Amp

Ibanez SW100 100W Bass Amp

Fender Bassman 100 Combo Amp

Any help would be apreciated, i don't have as much as an ear for bass amps as i do for guitar amps.
You should probably take this to the bass thread for some good advice on which amps to choose.

From my experiences, a good 200watts would be necessary for a good improvment in volume.
