Finally got to play my new rig with the band last night. It's a Fender Pro 400 combo on top of an Ext Pro 115 cab. Kicked serious ass, loud as hell and I never heard it clip. It was blowing out some serious heat from the chassis fan, I guess one should expect that when it's pumping nearly 500 watts for 2 hours straight. My only concern now is that it holds up. Saw an ugly thread on a Fender forum where a guy's 400 crapped out and Fender's repair shop was taking their sweet time to repair it. Guess I'll see how it does.
