Need some advice on whether to get an Ampeg 4x8 or 2x10. Both are available for the same price, have the same power rating, same relative size and weight. Which one would be more suitable for a cover gig that covers rock, funk, and some metal? I will be using an 350w head and another 1x15 cab with it. I tried them out in the store, but it's SO hard to make any judgements in a store. Any suggestions? Thanks in advance.
