I haven't a lot of experience with watts and power, but would the 20 watt VH Mini be enough (through a 2x12) to keep up with an acoustic drummer ? I keep getting mixed messages. Some people say I'll need more like 50 watt, and some others telling me 15 is enough?!
Well it depends on the drummer and how much "clean" do you need.
In this case I'd say that Diezel's has enough presence to be used way lower volume than other amps, meaning that to hear it you don't need to push master so 20W with 2x12 could be enough!
