Im looking to upgrade my measly swr morkingmans 15 combo to a gk 700RB-2 head and a 4x10 cab. I want something thats light on my back and will do well in a cover band. I am currently looking at an Avatar neo 410 and a GK neo 410. Dont want to spend more than $500 for something new or used. Anything come to mind from you experienced bass players? Thanks!!!
