Only one PODxt and we have the HD147, so why not? IMO, it sounds slightly better, and looks a lot cooler. But most of the gear is never seen because the stage is pretty empty without stacks.
Now that I've established that, let me tell you why...
So, it turns out my amp isn't blown at all. I ended-up borrowing a friend's stack only to find out when I plug in my guitar it did the same thing (nothing coming out but buzzing --I had to turn it up all the way just to hear my guitar a little bit). So I started thinking "hey, maybe it's my cable or guitar input". After changing cables and also cleaning my guitar input, it still was doing the same thing. In frustration, I put my guitar down face-down on my lap. By happenstance, I look down and see a panel on the back of my MH400NT LTD that says "Battery Pack". "OMFG!" I thought to myself. Sure enough, I swapped out batteries, and now my "blown" amp works fine.
Reminds me of an old story about the bassplayer in Manowar who had no sound in his live rig, and yelled at the bass tech for a while until he turned on the volume knob on the bass. Classic
