Uhh....you mean 5/64 and 4/64, right? 5/32 action is nightmarish, at least to my fingers. Lol
On my PG, she is set at .007 relief and just over 2/64" treble at 12th, and 3/64" bass at 12th, no buzzing. This one was setup remarkably well from the factory, and I've really only tweaked their initial setup parameters. The only major changes I've done, besides upgrades/cosmetic things, I did a full fret level and dressing. That was the barrier to getting that low, but to be honest...I think it got me maybe 1.5/64" lower action. It didn't really need the fret job, I was slap happy already.
