Hey guys, I just lowered the action on my bass a few weeks ago by lowering the saddles on the bridge. I've searched on the forums and there are loads of threads about truss rod adjustment but none addressed my issue. My question is: do I need to adjust the truss rod? Is it an adjustment which is vital for the "health" of the bass or is it something about how I'd prefer it to be? I personally would like to have lower action and heavy attack, I have read one of the stickies in the technique section (it's called "Demystifying Metal styles...", I don't play metal, but still...) and it says that some people keep their basses at zero relief. Is it something doable without any other adjustments? Again, I've seen lots of threads on how to, lots of videos by pros, but I don't really get why I have to do it or should do it.
