I am new to pro gear but I need to get soon a head and a cab. Thank you all that replied to my previous posting. I went from ignorant to entry-level. Reading all previous posts on Avatar, I decided on buying the B210. But I dont know which one is recommended: - Carpet, tolex or heavy duty? - 4 ohms or 8 ohms (I am only getting 1 in the meantime) I also need to get a head to match this cab that is below $400 USD. Please help me out.
