In the practice range amps..ampeg 20 and 40 watt... Rumble 25 and 40 watt.... Anyone have owned these that could give me some usable info. I can't get to a store to try them out so maybe someone has. I don't care about gain in a bass amp. I'm looking at tone and volume while staying clean. The 40 watt versions of both seem to differ in that the rumble offers push button voices, more eq options, and is ported. The ampeg has a 3 band eq and a 60 degree tilt option. Also the rumble has an xlr out. Any thoughts?
