My new band tunes everything down 1/2 a step. My old band had a gig recently and they tune standard. My MM Sterling had been up to the task. It was in its gig bag until last night. I detuned to practice some songs and found the action was VERY low, especially at the nut, 1st fret area on the D and G strings. So low that I thought the bass was already detuned. A quick check showed that it wasn't so I played on. After a bit, I realized that the action was a lot lower than it ever has been and thought about tweaking the trussrod. I searched around TB and found some good tips, but when I tried to turn it using an allenwrench, it wouldn't budge either way. Now, to clarify, I'm turning it perpendicular to the neck, using the wrench as a lever. I was afraid to use brute strength because it simply wouldn't move. Would detuning necessitate setup changes? I've been waffling back and forth between standard and -1/2 tuning the past few months. Wonder if it caught up to me... Advice?
