I'm a high school student working a part-time job that plays about 2 gigs a week. small to medium sized gigs where PAs are not always available. i want to upgrade my whole rig but have it easily separated into chunks. for this i was looking at the carvin b1500 head and either carvin 12's or avatar 12's. Unless there is another product for the same price or less, i only want to know which one i should be looking at. I was able to open up for he is legend this weekend and their bassist uses 812's and there is no lack of low end, so im not looking for anything bigger than a 12. portability is also an issue since my band is going on tour in a small van. any opinions?
