Half step down tunning, does it need truss rod adjustment?

Well, that. I'm tunning down my RG a half step down. Common sense indicates that the less string tension would need less truss rod tension to compensate, so I loosened it a really REALLY tiny bit.

Am I right?

And also (I dont want to create another thread), during what seasons do you make truss rod adjustments?

I wouldn't really be adjusting the truss rod without evidence that I needed to. You may have needed to adjust it for the tuning change, but you may not have. Really the only way to know is to measure and evaluate, unless its very obvious.

You may never need to adjust it seasonally, it depends on the neck and the climate.

Try to get a measurement of neck relief with a set of feeler gages, or sheets of paper. If the neck relief gets too small, you need to losen the truss rod. I can't think of a good reference, but I believe it's best to adjust the truss rod without string tension.

For me, seasonal truss rod adjustments are 1/8" of a turn at most, and usually when the humidity goes low in the winter, then when the humidity comes back in spring.

I have never had to adjust the rod for a half step of tuning.

You should check your neck relief periodically regardless of what tuning you have on the guitar. Changes in temperature or humidity could necessitate an adjustment. If I haven't played a guitar in a while, I always check the setup.

Well, talking about that, how'd you all set it up for a standard low action?

I like about 0.3mm of relief measured at the 9th fret (measurement done with a capo on the first fret and hand-fretting the 24th fret). I like about the same clearance at the first fret if possible. Then I set the string height at the 24th fret so that the 2mm mark on my ruler is right in the middle of the 6th string and the 1st string is at 1.5mm.

Cool. Mine is about 1mm at the 9th fret, and I can get it at 1.5mm on the trebble side but it buzzes at 2.4mm in the bass side. I'm guessing bad fret work?
