Also be sure to compare the Rumble 350 Combo to the original "giant killer" that started the high end - high wattage 2 X 10 bass combo rage => The one! The only! And still heavy wieght bass combo champ of the world! THE SWR RED HEAD!!! 400 watts and and damn near 100 pounds. $2,349.99 MSRP.
There's a lot to like in the Rumble 350 Combo. It's only $649.99 MSRP (or $450 at Musician's Friend) 350 watts and only 65 pounds.
Not as versatile as the SWR Red Head, but still a great sounding bass combo in it's own right.
Unlike Bro. Dave, I happen to like the overdrive in Rumble amps. It offers a lot of flexability that many stomp boxes do not. I also like the built in Dyna-Comp adaptive compressor. It works and it's unobtrusive.
I would play any average bar with either a Rumble 350 or 150 combo with complete confidence that I would sound: Great; BIG, Solid, and totally professional.
