It has been about 3 or 4 weeks since I picked up my ESP LTD B-206. The bass had a really light set of strings on it. Measured with my calipers: B .130" E .08" A .07" D .048" G .03" C .02" The setup of the bass as I received it was laughable. Intonation was way off and the action at the 12th fret was too high to be practical. I have lowered the action and set the neck relief to be small enough to disallow any fret-buzz at the first 5 frets. Repeatedly, over about a weeks time, the neck relief decreases to the point where fret buzz reappears in somewhere in the first 5 frets. The last time I adjusted the truss rods, I ran out of thread (i.e. no more adjustment available). Has anyone else run into the problem where the string tension doesn't seem enough to allow for adequate string relief on a bass's neck? Is my only option to get strings of higher tension?
