Hi,

2018 Collings D1A

Relief .014” at 5th fret 1st and 15th fretted (Collings specs .005")

Action at 12th fret
Treble 5/64” (Collings spec 2/32 or 4/64)
Bass <7/64” (Collings spec 3/32" or 6/64)

That relief calls for a truss rod tweak. I've done this on other guitars with no problem but would like a refresher.

I think...To flatten the neck, less relief, I loosen the truss rod meaning a counter clock wise turn of the truss rod. Right? I'll do it in 1/4 turn max intervals.

Since action is maybe 1/64 high this means take ~ 1/32" off bottom of saddle...right?

I read elsewhere a member suggested working on saddle first but I think I should be adjusting the relief especially since mine is high and I'll be flattening the fretboard by .009" In fact that may actually lower the action a hair even though that's NOT how you lower action! Right?

Any advice appreciated!

Tighten the truss rod to flatten the neck with close attention to any change in intonation.

I realize this post is old, but relief and action are two distinct and separate measurements. Always set te relief before adjusting the action.

larrivee's truss rod wrench (you might describe it as "offset") is the easiest one i've found. the one you would use is their item T2. i think the reason that the one collings sells (simple "L") is so hard to seat (at full string tension) is, if you can't seat it, you can't over tighten.
