70s Gibson maple twistyneck spotters guide

I've had several 70s Gibsons with maple necks that are twisted. If I was lucky enough to get the truss rod to work, the best I could get was "too much relief" on the bass side and "not enough relief" on the treble side.  If the guitar had an adjustable bridge, it would end up looking like this:

Not saying this guitar falls into that scenario, but it IS a 1978 with maple neck and has the bridge adjusted cockeyed. (photo stolen from the internet)

I'm in the market for a 175 but I think I will stick to a mahogany neck.

NOT ALL MAPLE NECKS TWIST REGARDLESS OF BRAND.

But I've owned several 70s Gibsons that did.

I had a slightly twisted neck on my PRS CE-24. They made a replacement neck from the same woods. Sent it back to the uk where it was fitted and sent on back to the shop. That one was slightly less twisted, but still not right. I then sold it on. 

I usually prefer maple necks. 

Twisted necks are probably why Rics fit 2 truss rods.

The Ric truss rods are kinda unique. You’re not supposed to use them to move the neck. You’re supposed to remove strings, loosen truss rod nuts, clamp neck to desired amount of bow, tighten truss rod nuts, reinstall strings to check action.
 

If the relief/action isn’t where you want it then, you have to repeat the whole process

 

in 2022 they switched to a single truss rod, but I’m not sure off the top of my head if it’s single action or double action

Most of my guitar necks are twisted a little.  All of them seem to twist that same way, with the low side relief more than the high side relief.

I wonder if 3 bigger strings on one side vs. 3 smaller strings on the other side, that are usually tuned to concert pitch its entire life has something to do with it?

That was applicable to the much older 4000 basses. 

The Rics TRs now work just like any other brand does. I use the same amount of turn to both rods with the strings on. I get it just where I want it and it stays there. Remarkably stable really.
