Hey guys. I've been having ongoing issues with my 2007 SVT for months. It's crapped out on me at 3 shows now. Bought it "New" off the floor at the local music shop about 9 months ago. They have had it in a few times and for over a month a one point. Last night we were playing an out of town gig and I turned it on and POP! burning rubber smell..... New club professional stage and nothing else was running on the outlet. Thankfully we had a back up amp with us. Anyways I told the shop I want my money back as I will never be able to trust this thing again. I was originally going to get another SVT but then I got looking at the V-4B. I like the fact that it is half the weight and has the option to use single 8 ohm cabs as well. It's obviously 100w compared to the SVT 300w but do you need 300w tube heads anymore? Any thoughts from anyone who has had either or both of these cabs would be great. Thanks again guys.
