    We played a small outdoor gig Saturday. During sound check the sound guy comes up with his tablet and says, I'm getting no highs from you, play a note.". I play and he shows me some sort of frequency thing and sure nuff nothing over 400hz. I reach down and grab my tone and crank the treble, on a Pbass using EMG Geezers with stock pots and harness, and up jumps the response and he says there it is and is happy.

    Is it normal for a tone control to kill the response that low? Am I confused with all of this?

    Does this "sound guy" have ears?

    Yes, they were prominent and evidently worked well.
  4. He did realise it was a bass guitar and not a treble guitar, right? ;)

    Yes, a passive tone pot will roll off treble with a very gentle slope. So a roll-off that starts around 400 (or even lower) is perfectly normal for a regular passive P. Then when fully down it will actually create a little resonance peak in that 200-400 region. (A lot of players quite like this.)

    Thanks much. I never realized how much of a bass is packed into a relatively small amount of sonic space. Makes me rethink how I'm setting things when not getting FOH help.

    I'm highly opinionated and extremely self-assured
    Also, remember that the frequency scale is logarithmic, not linear. From 40Hz to 320Hz is three octaves.
