I got a Rumble 100 recently and it does a good job. I am in a classic rock band that plays for mostly older crowds, like my age, and I line out to the PA with either a passive direct box or the mxr m80. I can usually hear the deep lows coming from the PA speakers.
On a side note about weight,
Our new keyboard player has a big 1x15 Behringer combo that weighs 3 times that of the Rumble 100 and he doubles on guitar and has another guitar tube amp. If we get back to being real busy I want to see how he holds up. He bought ramps for the drummer's big trailer and yesterday, for the first time, we rolled his loaded cart of equipment into the trailer. Instead of buying ramps he should have gotten a lighter amp.
