Recently acquired a '80's-something MIK Squire Jazz for free, basically (bartered with some consulting work in lieu of payment). Anyway, setup was horrible on it...the strings were almost 8mm above the 12th fret!! Ok, no problem, im thinking it just needs a decent setup. Truss rod works fine, so i tighten the thing to the point where theres actually BACKbow on it, i.e., theres now a hump on the fretboard. I tighten up the strings and the bow is back. Pulled off the medium gauge strings and put on some lo-tension lights. It helps, but still has an unacceptable action. I wouldnt mind dropping $130 on another Squier neck, but id be really miffed if I got the same result . Thoughts??
