Uneven bow between bass and treble side?

    On my bass (a 2008 MIM Fender P-Bass) the neck "bows" slightly more on the bass side (e-string side) than the treble side. When I press the first and last fret down on the e-string, I have more action at the 12th then when I do the same to the g-string. I think my neck may have a twist, but I'm not sure. Is it normal for the e-string to have more "bow" on the neck? If this is a problem, I can see it getting worse, since wood tends to do it's own thing, so I may have to replace the neck :(

    BTW: The bass is, at least at the moment, still playable.

    I setup & repair guitars & basses
    Press down F1 & F15, not F1 & F20whatever, check @ F7 for relief.

    The neck is twisted. Not uncommon. Also, not a major issue if you have slightly more relief on the bass side than the treble side. Unless it is radical, bass necks with a slight twist can generally be set up to play well.

    Do you have the same problem if you take the strings off?

    the majority of basses i own and play have slightly more relief on one side than the other. vintage or modern. they all still set up with "blow on the string" action.

    How far off are they....I checked and all three of my basses have a Credit Card width on the G (1st fret-15th fret checked at 7th) and touch the 7th fret on the E string. So I guess all my necks are warped?

    There's a reason why some basses have dual truss rods. It's for those who actually worry about stuff like this (as well as for wide 5-string+ planks).

    Again, this is NOT a bad thing. In fact, it actually works out quite well, because the lowest strings will scribe a bigger arc when struck than the higher strings, necessitating a bit more clearance. Logically then, it actually MAKES SENSE to have a tad more relief on that side of the fingerboard. This is what usually makes basses with this "defect" an easy setup.
