AMP BH-420 / Peavey Classic 400 / Berg NV610 Stack!!! Was goofing around with 2 new toys that the UPS guys dropped off today. The AMP BH-420 and the Berg were on my doorstep when I got here (what a great day huh???). Had to hook up the Peavey 400 and the AMP to try em both out with the Berg. One word.....AMAZING!!!!
