My Dad is a pretty successful guy, and he's the type of guy that gets excited about stuff and has the money to indulge himself when he gets excited. Anyways, he saw my band a couple of nights ago, and I guess he liked us, because he heard me say something about how I wasn't really happy with my bass amp (i'm using a yamaha powered mixer...).... so he buys me a freaking Ampeg SVT-4. Wow! Anyways, I'm not sure it's working completely right.... My cabinet is an 8 ohm Avatar B410, and after reading through the reader's manual a couple of times, I got the impression that an 8 ohm cab was safe to use with this amp. Well, for one thing, i haven't been able to get it to work when I use the speakon cable that came with the amp. It turns on and everything, but no sound. I tried it out with just a regular old 1/4" plug, and it seemed to be working fine, but then it kept just cutting out with the little red peak light next to the gain knob lighting up. I had it at very low volumes - at first i figured it was my bass, because I had had problems with it having a crackly connection (I bent the input connecter closed a little bit and it hasn't been as much of a problem), so I figured that was the problem, BUT when I unplugged the bass it kept doing it - even if I unplugged the cord from the amp altogether, the little red light was still turning on and off sporadically. I tried it with another bass and had similar results. No obvious damage signs like... smoke or a hum or anything. I just turned it off and then turned it back on without anything plugged in at all and the peak light isn't turning on or anything, but I'm afraid to plug anything in because I don't want to damage it. Anyways - what's going on? Is there something wrong with the amp, or am I connecting something wrong? Any feedback would be GREATLY appreciated.
