My '91 Thumb Bass has always had a very low action, could be considered too low but it never gave me any problems. I never had cause to adjust anything other than the nut and the bridge when I first bought it new and set it up to suit me.
Last night I did a stand in gig with a band that tuned to E flat, I did that but felt there was some slight buzzing from the lower tension strings. The neck relief appeared not to have changed so this morning I thought I would relieve a bit of tension on the truss rod. The head on the rod felt slack, could easy turn a quarter each way without feeling tight. Turning it over half a turn anti-clockwise it tightened up, turning it clockwise felt like it was just loosening it.
I watched the Warwick video on replacing the truss rod and decided to remove it to inspect it. It is the one way aluminium rod. On looking at the way it worked turning it anti-clockwise tensioned the rod.
So the thing is, there was originally no tension on the rod and there was very little relief on the neck with 45-105 strings on, shows how strong the neck is, but I need a bit of front bow.
The question is, could I install the rod the opposite way around so tensioning it would increase the relief?
