Okay, so my new Avatar B212 Neo came in today. I unpack the thing, and excited to play it, plug my Eden WT-300 and bass in. What I got was fuzzy, distorted, and quiet. I then noticed that there was tape blocking the ports. I removed the tape and it still sounded distorted and quiet. Could I have damaged the cab playing with the ports blocked, even for a short time at low volume? Trying to play the cab now results in a quiet, distorted sound, but despite this, my head gets hot enough to run the fan. I also tested my head, into the speaker of a guitar amp. I did this quietly as to not blow it, but it was clear that the amp is working. Help? I'm guessing the cab was bad when it got here, and I have a return on my hands.
