PLEASE HELP!!!! I'M GONNA BLOW SOMETHIN UP!!!

Discussion in 'Amps and Cabs [BG]' started by mebusdriver, Mar 19, 2003.


  1. O.k. I'm now running an Ampeg B2R head through and SWR Workingman 4x10. Now the head is hooked up to a compressor (I'm not sure what kind). And the problem is that when I have the head hooked up to the cabinet is sounds great (the best tone I've ever gotten) but; when I hook up my Ampeg 6x10 Classic everything starts farting. Not the Ampeg just the SWR. I've gotten it to stop but I have to turn the master volume way down. And also when I slide anywhere from like the 10th or 12th fret to below that (say around the 15th) my speakers also fart or clip. Now how can I get this to stop? Playing below the 12th fret is a must for me and I can't do it because whatever I hit makes the cabinet clip. I've got plenty of room for wattage cause the Ampeg can hold up to 1200 so I can't thing of anything that would fix this. Thanks.

    Eh, play softer when up high?

    You probably don't have enough power. Your B2R is only 200 watts, and the amp is clipping. Why you are only hearing it through the SWR is a mystery, though. What are the ohmages of the cabs, and what ohm outputs have you got assigned to these cabs? Inquiring minds want to know.

    ohm loads? Sound like those could both be 4ohm cabs....

    The SWR is 8 ohms, the Ampeg 4.

    This makes almost no sense.
     
  6. I'd say try the SWR on a different amp. If it farts out, you've got a blown/damaged SWR cab. In that case, have it looked at.

    Yeah, but he says that it's the Ampeg that starts all the farting. Then says it's not the Ampeg. . .

    From the title, I thought this was a terrorist threat - stop the attacks or we will blow up all your amps!! ;)

    You have a mis-matched ohm load when you have both cabs on. Looks like your total load is somewhere around 5 or 6, which is probably freaking your head out. That coupled with a low power head like the B2R is causing your problems. Match up your ohm load and you should be ok.

    Oooooohh. Both cabinets on at the same time?

    The total ohm load in that case is 2.67 ohms, which that head probably can't handle. Don't do it.
    Use just one or the other, or two 8-ohm cabs, or a head that can handle 2-ohm loads.

    Unless the head is stable at 2.6 ohms, check your users manual online to be sure. I thought some of the WM cabs were 4 ohm, at which case your total load would be 2 ohms, which is probably a no-no whether the manufacturer says it's a good idea or not. Second off, what the heck do you need ten-10's for anyway??? :eek:
     
  16. Yeah, both amps at the same time. The SWR farts and the ampeg is fine. I also have a workinman 4004 head. Do you think that would be enough power? And you're saying I need to match up the ohms on the cabs. So my ampeg has an ohm selector on the back. I think that's what that knob is. Could switching that work? Or do I just need to have more power? I want six tens because I can. And umm, we practice really loud.

    First, I'd suggest reading the FAQ to find out about ohms and cabinet impedance and such.
     
  18. Why not just use the 6X10? I'm sure that would do fine for a practice. Try getting by with a 25 watt amp! :D
