HI guys... I need you expertise on something... I have recently purchased an old early 80's bass from ebay, and when I got it, it had an extremely high action, so I plugged it in, and it has a real SWEET sound, and a little 6 way tone selector that is just genious in a passive bass. This bass is neckthru and I really like it... However, when lowering the action It started buzzing quite a bit and on closer inspection, this thing has been refretted but in a VERY ****ty way. they have slapped the frets on and most have never even been filed. (it was a home job for sure). If that was the only problem I'd be happy, but the neck seems to have a bit of a belly from say the 3rd fret to the 6th and it dips a little from the 9th to the 11th on the right side. the left seems to be straighter. Now, since I really like this bass's tonal range and apart from the warping, it does have a really nice and confortable neck, Im wondering, is it possible to get the neck straigtened out? Would it be a really expensive thing to get a luthier to do? I mean the normal setup around here is about 30. Is there something I can do to help it get straighter like hanging it by the neck or something? Thanks for your help.
