I'm looking for a new amp soon, two of the main contenders have been the tungsten crema wheat and the cutthroat audio Down Brownie. I don't really need cleans in a live situation per my playing style (If I did my Rivera M60 covers that ground nicely). I really like the footprint, look, and sound of both the brownface and tweed deluxe style amps but I'm wondering if they could really keep up with a loud band without PA support? I've got my own PA but don't always want to bring it out for gigs. My only tube amp has been my M60 and my tech says its outputting about 45 watts RMS. Really great for cleans and it gets LOUD. I love 1x12 so the Tungsten and Down Brownie seem right up my alley, but is 20 watts enough or will the amps be pushed to their absolute limits in a band situation?
