A new set of strings forced me to fiinally adjust the truss rods on my 4001. It all went off fine and the neck is now optimally adjusted (according to Joey's Rickenbacker Pages, which have disappeared!) and this allows me to set the action very low which is fine. But.. this fiddling about has resulted in the intonation drifting on the E and A strings. When I come to adjust it I find that the screws are partially hidden as the action is now so low.
Is there any trick to setting the intonation or is it a case of raising the action high enough to reveal the adjustment screws? If I did this, would the subsequent lowering of the bridge cause any drift in the intonation again?
