I own an Avatar 4x10 and it is a great cab...no complaints. Infact it cuts through the two guitars in our band just fine, but I am still debating adding either a 2x10 or 1x15. I think the 2x10 will allow me to be more portable for small venues, but the 1x15 will give me some more "rumble". Your opinions are appreciated...anybody using one of these set-ups from Avatar? thanks!
