    Rickenbacker has used dual truss rods on their basses for a long time .

    ive been putting dual rods in my basses since late 80s early 90s. I use them sometimes on 5's, depending on neck woods used, and most of the time on 6's or more, unless im using multi-lam super hard woods in the neck construction. ive also been constructing the necks so the rods are removable just as long. I almost always make the rods removable unless im doing some kind of off the wall different build and the rod is adjustable from the body area in a neck thru build. I rarely do this anymore. if its a one way rod, which I build myself, I am able to take the rod out spin it 180 degrees and reinsert it if any backbowing of the neck has occurred with the rod in neutral tension, I am able to remove it. check the video spinning the rod and reinserting.

    I also would use double rods in 8 or more string guitars, unless its a super hard wood multi lam. (bubinga, purpleheart, etc)

    <edit> ok, video wont work, ill figure it out. I think its something to do with photobucket and mp4 files......

    I've been itching to use the one we have at work, seems like it'd do a fantastic job with the figured maple blanks I have.

    The way I see a truss rod is that the wood taken out isn't as strong as the rod put in. The only time, IMO, that you'd make the neck weaker with a truss rod is if you route too deep or carve the neck too thin.

    3" blade, damn things are expensive. I need to figure out how to sharpen them myself or find someone who does it for a reasonable price. I tear them up cutting a lot of snakewood and other dense hard woods.

    we have several local sharpening services here that will pickup and deliver for a pretty reasonable fee.. I'm betting there is someone like that in your town.

    What direction do I turn my truss rods in my 8 string? Right tight? Or are they special? Dual truss of course...

    normally, turning the adjusting nut clockwise will produce a backbow while counter clockwise will produce a forward bow. but as with any truss rod always procede with caution.
