    I've got a 2005 MIM Jazz V that is determined to keep bowing forwards even after a setup by a tech and my own frequent adjustments to the truss rod. I was hoping you gents may have a solution that doesn't end in me buying a new neck or a new, higher quality bass.

    I’ll preface my comment by saying that I’m a huge fan of the MIMs, and own several of them.

    In my experience, a Jazz V in good condition shouldn’t need frequent truss rod adjustments unless it’s being exposed to drastic temperature/humidity changes or it’s constantly being restrung. I haven’t done a truss rod adjustment on my V in something like three years, and I live near salt water with annual temperature swings from -10°F to +100°F.

    If a qualified tech has verified that the truss rod is functional and has done a proper setup, and the neck is still bowing unexpectedly, a neck replacement may be in order.

    To be quite frank, that piece of wood just might not have wanted to be a neck. A truss rod can only do so much. As stated before, a new neck may be in order...

    Agreed, that sounds like a bad neck. My MIM Jazz 5 is solid as a rock through some pretty wide temp and humidity swings here as well.

    Thanks for the advice guys. I've been thinking for a while about buying a custom fretless neck from Warmoth for this bass as Fender doesn't make a fretless V Jazz. So this may be the opportunity to do so. The only downside is I lose my little Fender decal and along with it any resale value.

    I did purchase it new and I wasn't aware the warranty was lifetime. Sounds like something worth investigating, Thanks Bob.

    I've been doing some thinking about taking the neck to a tech to have him take off the fretboard, replace the truss rod inside and stick a new fretless fretboard on. Would replacing a fretboard this way be possible? And would replacing the truss rod be a likely fix for my bowing issue?

    Leo’s modular design for Fender guitars and basses was initially conceived as a methodology for facilitating neck replacements. So while a truss rod replacement is certainly possible, it’s definitely not an easy task.

    I’d venture to guess that a new fretless neck from Warmoth would be cheaper than luthier surgery on your existing neck. Either way, modding an original MIM — headstock logo or no headstock logo — won’t really preserve the instrument’s resale value.

    Bobster’s advice on consulting an authorized Fender dealer on the warranty issue would be a good starting place.
