I've just noticed in the specs that the Epiphone T-Bird Pro V has a dual action truss rod. All of my basses have 'normal' truss rods & I recall that on the Squier musicmaster I used to own, It had quite a chunky neck compared to my mustang & TI Jazz flats didn't had enough tension to pull any relief into the neck, so I had to use heavier LaBella strings instead. I'm guessing that if that bass had a dual action truss rod, low tension strings would have been OK?
Any other differences with a dual action truss rod? Is there anything different I would need to keep in mind when doing a setup on a bass with one? I've sold a couple of basses this week, so it looks like a T-Bird Pro-V with natural oil finish might be coming my way soon if I can work out a way of making the missus think that its her idea that I order one.
