Just drummer? No guitards?
The idea of the overdriving pedal is saving on carting huge tube amp. You have three concerns, weight, volume and budget. I could plug fizz pedal in front of a very little amp and play a coffeeshop with a jazz drummer. So get real and provide some decent info if you want advice that isn't "get my favourite amp". Nothing wrong with a d180 if you can find one.
