so, i think the jackasses who did the work on my jag f@cked it up the first time. when i opened up the inside of the trem mechanism, the screw for the lock was way, way too far in. so much so that, in fact, the lock wouldn't actually lock anything; it would just butt up against spring. so THAT'S fixed.
i also got rid of the new lil screamin demon in favor of an older lil 59, and not only is the tone better, but the pickup claw fits it now. i have no idea what (if any) difference that makes sound-wise, but the axe definitely looks more aesthetically pleasing with both pickups having a claw.
the guitar even intonates now. . . except for the 6th string. if i raise the action, the buzz goes away. if i lower it, the string intonates but with terrible, terrible fret buzz. any ideas? i'm playing with 11 - 49 guage strings, tuning down 1/2 step.
