buzzing in speaker sound

Discussion in 'Amps and Cabs [BG]' started by bassdementia, Aug 3, 2001.

  1. I have a Carvin Pro Bass 300. its a combo amp with 300W to the head and 400W to the cabinet part. a 15" speaker in it. the problem is when i turn up past like a 7 on the master volume and a 7 on the bass volume the sound that comes out starts to buzz, sounding like a tear in the speaker. ive checked the speaker and its fine with no tears or anything. i want to use my footswitch to volume boost it without getting the buzz. it also has a tweeter switch from full to cut on the back of the cabinet part.

    Sounds like clipping.
    First make sure that pre-amp gain is not set too high (there should be no distortion with the master set at low levels)
    How do you set your EQ?
    If you dial in a lot of bass, the amp will run out of headroom even if you do not crank the master volume, because lows eat up a lot of power.
    If your amp is not loud enough, leave the bass knob/sliders flat and boost mids instead. This may sound unpleasant if you're playing alone, but should be ok in the mix.
    Check out the current thread 'midrange - yes or no' on that topic!

    Good luck,

  4. I had speaker buzz once I went past a certain volume (less then half way).

    Turned out to be a tired speaker with voice coil rub.
    Recone solved the problem. Back to cranking it up and tonal bliss.
