Congrats on your first ExFactor! I'll try to help you here.... First - do not use a phillips screwdriver on that truss rod nut. It is a + pattern but made for a wide straight blade screwdriver. See if you can loosen the thing first before you try to tighten it. I always assist mine by pulling back on the headstock while tightening... and no more than 1/8 or 1/4 turn max at a time. Even though the necks are laminated, mine still need to be adjusted about twice a year, and they can feel tight. I've contemplated removing the nuts on mine and applying a little bowling alley wax to lube them up but haven't done it yet. I spoke to Mike Haney a couple of years ago about the possible eventuality of these things bottoming out. He suggested adding a washer, though recommended sending it to him for that. Good luck with sorting that part out.
The saddles just screw in and out of the saddle blocks, 1/2 turn either way, to set the height. Out of 3 of these, I have 1 or 2 saddles that turn freely by hand. All the rest need a small wrench to turn. DO NOT get carried away and run the saddles down so far that they make contact and crack the bridge/tailpiece assembly frame. Don't even let them touch the frame. If that doesn't get the action low enough, then you have too much relief. Always set the relief first before saddle height (on any bass).
Those big phillips screws that sit at each saddle are for adjusting intonation. They are tightened COUNTERCLOCKWISE up to the underside of the frame to secure. You can crack the frame if you try to "loosen" it further by going more counterclockwise.To make an adjustment, turn it clockwise to allow it to free float within the channel. Once set, turn it counterclockwise again to secure it in position.
Hope this helps
Brother, thank you so much for taking the time to write this all out for me, truly appreciated. I will do my best to try an use some of these suggestions on her tonight. I may reach out to you via PM if i have any other questions if you don't mind?
