I just got my amp in the mail today. An older model of the TNT 115-BW. This is th biggest amp i've ever owned. I bought it off EBAY. The amp is great, but it shorted out (it just stopped playing to about 5 seconds and then came back in). Im going to see if the problem clears up. I know some of you guys and gals have rigs that have a power amp, pre amp, and 2 0r 3 cabs, but this is a big deal to me!
