Why does my treble pot have a wider, more obvious range and the other eq knobs are more subtle?

    I have a '72 Traynor YBA 1 Bass Master. I don't know a lick about amps, let alone tube amps, and I'm curious if something is wrong with the amp. It's old so things can happen over time. I just purchased it off Reverb. I can get the eq I want out of it but my other amp, an Ampeg B5R, has all 3 eq pots working with equally wide eq sweeps.
    Is this something an amp tech could fix? Does it need fixing?

    I appreciate any of you knowledgeable TB folks chiming in.
    :)

    Human hearing is more sensitive to treble, so small differences may seem great.

    Bass and Treble are often shelving eq’s which have a wide range — “everything below/above X”

    EQ isn't designed the same from vendor to vendor. I'm pretty certain that Traynor and Ampeg have different EQ implementations.
