Hi, this is Raven T. Mitchell, expert with Dean Guitar, and in this clip we're going to show you the proper way to adjust your truss rod. Now, in some cases, some people say that this is tuning a truss rod, but in actuality, it's just an adjustment. What we have here is a six on six or three on three six string guitar that we're going to adjust the trust rod on. The first thing you want to do is this has a truss rod cover. We've got to get to that so we're going to loosen the strings and I'm only going to loosen the top four. There's really no need to change the ones on the outside because they're not going to get in our way. Once they're loosened up, I'm going to move them to the outside so that I can get to the truss rod cover. Next, we're going to take our Phillips Head Screwdriver and remove the screws that are holding the cover in place. Of course, doing that as carefully as possible, not to scratch your guitar, also keeping track of the small screws that come out of the truss rod cover itself. Once you get the screws removed, remove the cover and you have access to the cavity where the truss rod is. Now in this instance, most truss rods have a four millimeter Allen wrench that you use to adjust. On some guitars, like your Les Paul and Gibson style, they use a barrel style truss rod adjuster. This is an example of one of these truss rod adjusters. But this is not what we need for this guitar. We just need a regular one that has an open end where the Allen wrench goes in. Now, if you're turning this and you go, tighten the neck, if you're tightening the neck, you are lowering the action of the truss rod. If you are loosening the neck and turning it that way, you are raising the action of the truss rod. In this instance, we have a, what's called a relief in the neck where it is bowed, so we're going to tighten the neck and take some of that action out of the neck. Using small adjustments, quarter turns at a time, that's going to let us know how much we need to adjust our neck. Everybody's neck is going to adjust differently so adjust your guitar neck appropriately. Once you've adjusted it, go ahead and take your cover, put the cover back on your guitar and replace the screws. Doing everything in reverse order. Next, take your strings and put them back in the slots in their correct position and there your guitar neck has been adjusted. Now that's the proper way to adjust your truss rod. This is Raven T. Mitchell, expert with Dean Guitars.
