Great thread, I've been dealing/ struggling with this for the past few days. got a brand spanking new Ibanez Prestige 657 msk....
I've gone in lowered the action ever-so-slightly as per Rich Harris's instructions at Ibanez rules, and have been finding when I get down to the 1.5 1.6mm recommendation for "Low" that when playing on a crystal clean setting I can hear the occasional rattle.
what I've realized is that my technique could use much improvement lighter touch, Etc.
I'll also look at how I have things eq-ed
It's imperceptible on a high gain/ distorted crunch tone, just triggers my OCD, lol
