Does the JEM 7VWH have a double expanding
truss rod meaning the the user can control the both the up bow of the neck and the down bow of the neck. For example, you can only control the up bow on a Fender guitar with it's single truss rod. I would think that a guitar with the *design features and playability of the JEM would have a double expanding rod but I thought I'd ask.
All replies and advice is appreciated;
Thanks; *
