I have a '63 AVRI Precision that I LOVE. Split coil pup heights can be adjusted to match each string. No problem. I have a '75 AVRI Jazz which also has the 7.25" neck radius. Jazz pups are one-piece and cannot be adjusted for each string. With this neck radius, there is a substantial difference in gain because the E and G strings are substantially closer to the pickups than the A and D strings. Has anybody noticed this phenomenon and, if so, is there anything I can do to minimize this problem of gain differences.
