Double Truss Rod - One Loose?

Joey,
 
When are you going to make a video, like the Big Red Bass Guide To Adjusting Your Alembic?
 
I read that stuff, I'm still terrified.  I can't seem to translate it into really doing it.

Double Truss Rod - One Loose?

Man, I really am being persnickety tonight...
 
These values always fan out with the most tension on the big Es and Bs to the least tension as we work up to the Gs and Cs.
 
Nope. TI Jazz Flats and Rounds both have more tension on the G than the E or B (too tired to look up the C's right now).
 
But otherwise we agree (as usual) - you need to figure out how to deal with this stuff, if you want to maximize your enjoyment of the instrument. Even a great tech isn't going to know what's right for you, or have the time and patience to get it there.
 
I can't ever seem to blindly follow a rule like make them both the same. How do I know they've always been adjusted in unison in the past? Or that the wood doesn't just have it's own desire to twist, or that my string tensions are different, and so on? Even is a good starting point and rule of thumb, but that's all.
 
Brad - take a deep breath, read it again, take another deep breath, and then try making just one of the adjustments by a very slight amount, and see what happens. Make note of what you do, so you can put it back as it was if need be. Neck relief (truss rods) is the best place to start.

Well I was wrong, Bob.
 
A brief skimming of some string sites revealed, indeed, that the highside IS usually higher tensioned (want some bacon with that egg on your face, son?).
 
What I really meant to say is that I adjust each side of the fingerboard/truss rod on its own.  So that regardless of the strings, I've adjusted the relief on each side to the clearances I've determined work best.  After doing that, I have no idea what the truss rod tension are, but I truly doubt they are the same.
