I'm looking to do some basic setup on the Eastwood Wolf that I own, and wanting to learn more about adjusting dual truss rod guitar before I undertake this. Any good resources (youtube or otherwise) out there --or-- any pointers from personal experience?
Most guitars these days have a dual truss rod, not a biggie. Make sure the allen wrench is seated firmly in the socket, you don't want to start rounding it out this early in its life. Go slow, like 1/4 turn at a time and recheck your neck relief. If it has already been adjusted you shouldn't have to turn it more than 1/4 to 1/2 turn to start seeing changes. If it hasn't been touched it might take a turn or more to take out the slack and start meeting resistance and getting results.
Clockwise (looking from the headstock) to tighten and remove relief, counterclockwise to back off the rod and add relief.
Dan Erlewine would recommend measuring relief with the guitar on its side in the playing position (due to the effects of gravity), but I'm lazy and usually do it lying flat in the "set up" position.
I'm assuming that you know how to measure relief and know what relief you're looking for?
