hey im lookin for new rig. i am down to a avatar 4x10 and a GK head and the SWR workingmans 4004 with the 4x10 for 1000. no music dealers carry either GK or SWR so your opions are appreciated. and what kind of tone do each of these have? is the swr 4x10 1x15 worth the extra 250 dollars? and has fender changed the tone/quality of the SWR products?
