I see a new slogan here. Fender Rumble amps: Loosening bowels in a county near you
When I first started playing with my new band, I brought both the 500 combo and the 210 cab. Since I can't turn it up at home without being evicted with extreme prejudice, I would test out the capabilities of the rig during rehearsal. I was being a bit judicious with my use of the master knob for the first couple of rehearsals. Just before the third rehearsal, the singer says "I think we can all turn down a bit (looking directly at me while saying this) before my ears bleed". Message received! I think my master was set to just under noon, and it was shaking the room
When I was in a metal band, I would have loved to have had this rig. The one I had at the time was almost, but not quite, as powerful but lacked definition. It was still loud enough to compete with the gorilla on drums and the two guitarists with full Marshall stacks. That should be no problem for the this Rumble rig.
I really only need to bring the combo for rehearsal, it's been able to do the job very well without any issues.
