I have a Workingman 2004 amp and Workingman 2 x 10T cab but the thing flutters if I try to crank it. The cab is 8 ohms and the head is rated at 4 so I ordered up a nice new 8 ohm 1X15 Avatar to get everything matched up and get a more solid bottom end. Stupid 2X10 still flakes out on me and the whole rig isn't very loud either. I thought the SWR stuff was supposed to be real good? I have taken the 2X10 cab apart looking for anything loose and can't find anything. Made sure everything went back nice and tight of course. I don't know if it's possible that the 10" speakers are damaged or not, never have had that problem before. The cones look perfect and they do work just fine if I don't try to crank the volume. Then again, maybe it's the amp that's causing the trouble. The clipping light seems to come on early to me, but again I don't have much experience with that so maybe it's normal. Any suggestions to get the thing to get loud and deep? Do I need to replace that head or get it repaired or something? What head could I get cheap that sounds decent at least and caan play loud enough to jam with a good drummer? Or how can I check out me 210 cab to see if the problem is in there? Everything seems fine with just the 15" cab, but again not loud enough and the highs suffer. I have a practice with a drummer and guitar player this Sunday and I can tell it's going to suck because I don't have the volume I need for them. I don't think I'l be buying an amp before then either unless I can get something for under $200... Help please?
