I took my new B1500 to a gig last night. I have literally 10 minutes of playing time on the thing, and that was just at "in the house" volume. We get done setting up, and have about an hour before people are going to show up and we are to start playing. The guitarist wanted to go over something, so we did so. I had the EQ flat, the drive at about 50 percent, and the master volume on 3. Certainly not anything that should tax the amp at all. 3 minutes into the song, the bass cut out. I look back at my amp. Uh Oh. The light is off. I'm hoping and praying the power cord fell out. Wrong. As I walk back towards my amp.......that scent we all know and fear hit me. Then the magic smoke could be seen escaping. Damn. This amp had less than 15 minutes playing time on it and it fried. I guess tomorrow will show how good Carvin's customer service is. I REALLY don't want to pay shipping back to CA for an amp with less than 15 minutes on it. I also have A LOT of gigs coming up. Luckily, I was only a half an hour from home, and I had my new Markbass mini P121 combo. After a call to the girlfriend to meet me half way with the amp, it performed flawlessly... I just used the head portion of the combo into my SA410, and it sounded great.
