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.
