    Hi,

    Recently I bought a EBS TD 650 with a EBS 410(800W RMS)

    I first time I tryed it out was at a gig last week, it sounded ok, but often when I initially hit a string I heard nothing.
    It was only the first time, the times after that it did well!?

    The volume was at 6 o'clock so that's pretty loud, maybe the vibrations of the cabinet are too heavy for the amp or somethin'???

    A friend of mine told me that it has to do something with the noisegate from the amp??

    A problem with an EBS??? Something's definitely not right. Something puzzling that I would like to be sure of... What do you mean when you say the volume was at 6:00? Did you crank the volume all the way clockwise? Also, what are your gain and comp/limit control settings? Have you tried something a bit below full volume? :rolleyes:

    Here are a few things you can check. Unplug any effects that you might be using in the signal path. Check your bass cable, speaker cable and then the battery (if your bass uses one). If the problem persists, try another bass if you are able to. Can you test the head with a different cabinet?

    Once you've checked all of the above contact your dealer or EBS.

    I have a ebs td650 ran into bergantino cabs and have no such problem. Even when I turn up. Do the steps described as above.

    I tried the head with an ampeg svt 410 hlf cab. and the problem was gone, and when I placed the head on the ground or put a piece of rubber between the head and cab the problem was gone too.

    But the Ampeg doesn't produce so much volume as the EBS 'cause the ampeg is 500 w and the EBS 800w.
    And since my bass has major output and I'm playing in low B all the time, the vibrations of the cab are too much for the head, I think.
    And then the too heavy vibrations are shutting the noise gate from the amp, and when I hit the B string there is no sound produced, 'cause the noise gate had to be open at that time.

    Could this be the problem???

    Oh yeah I have a warwick corvette 5 string active,
    gain is at 9 o'clock and volume is at 2 o'clock and compression is at 9.

    Try turning the compression OFF.

    You mentioned that you had set the compression at 9. With a setting that high, your sound / signal may experience a significant loss, such as no B string sounding as you described. Try it. If it doesn't eliminate the problem, then at least you'll know that the compressor is not the culprit.

    The compression knob only adjusts the ratio and max value is 3:1. So it can't cause the problem described. That amp doesn't have noise gate either. I don't even think that this amp has any kind of protection circuitry. Its better to have the amp checked at least if it still has warranty.

    Okay, let's review. You use the head with another cabinet and it is fine. You use the head with a some shock protection and it is also fine. This narrows it down a bit. Perhaps the tube has come loose? As mentioned earlier, did you try another speaker cable? Failing that, it sounds like the cabinet itself might be the culprit.
