Tea kettle overtones on guitar tracks?

    When recording the guitars on my band's latest CD I have noticed that there is a constant "steaming/whistling" sound on the tracks that is similar to a boiling tea kettle.

    I am using an Ibanez SZ through Peavey JSX head with a Randall 2x12 with Jensens. The mic I am using is an SM57. It is going into my Behringer mixer and into my Yamaha XG sound card. I am using Sonar 3 to record.

    The cabinet is facing a concrete wall, but it is completely surrounded by thick cushions.

    I was just wondering if anyone has had similar problems.

    Can anyone think of a solution?

    That's probably a combination of mic'ing technique and A/D conversion. Try sweeping a high Q parametric EQ to find the ugly noise and dip it out.

    This may sound stupid, but how exactly do I take out the frequency?

    I'm not too familiar with multiband EQs, but I was playing around with it a bit and I think I may be getting the hang of it.

    Just to be clear:

    -what does Q mean/control?
    -what does the gain do?
    -do I need to use more than one band?
    -what does trim mean?

    Any help would be greatly appreciated.
  4. -what does Q mean/control?
    The width of the affected area, frequency wise. A low Q (0.5, ballpark numbers) will be useful for gently shaping the whole sound like adding or subtracting a bit of bass. A high Q (7-8 or even 45-100 depending on your eq and application) is useful for getting surgical - for example finding and eliminating that annoying overtone of yours.

    -what does the gain do?
    Hard to tell since we don't know what unit you use but you are probably referring to the gain of the EQ-band in which case it will boost or attenuate the frequency. ("Turn up the bass" on your average home stereo.)

    -do I need to use more than one band?
    For the problem you described - hardly.

    -what does trim mean?
    A way to change the gain of the overall sound pre- and/or post the eq section.

    Is the sound present at the amp?

    If so, it sounds like either a loose tube or a tube is ready to blow.

    Just a stab.

  7. had a the same kind of thing happen to me a few years back.

    we found this really old, but really sweet sounding upright piano in this old church hall. it sounded so good that we decided to use it to lay down some tracks on an album we were doing at the time.

    so its all mic'd up, i am in another room with my DAW, monitoring on headphones.

    So we got some levels, were going through the song , it was sounding great... until... ever so faintly there was a hissing/whistle sound. it wasnt all the time, just random.

    i sat there trying to figure out what was going on, in the back of my mind i thought a cap and gone in one of my mics.

    pressed stop, had a listen... guess its coffee/tea/milo/hot chocolate/ whatever the hang your drinking time!!!

    one of those old automatic urns hidden in a room down the hall from us.

    my dad's a fireman :p
