Double Truss Rod help!

[beelzelboss]

I have a Tobias Growler, and I am just about to set it up, but I have ran into something new. A double truss rod, and its not meant for an allen wrench to adjust it, so which tool should I use to get in there? It's under the fretboard a bit, and quite small, and I need something that I can do precises turns.

So first off, after searching a little I found that the right one adjusts the right half of the board, and the left adjusting the left end of the board. I'm shooting for just slight bit of relief, so I don't think that will be hard... It has too much relief right now, so counter clockwise turns (correct?). Just have to do 1/8 turns and measure it at the 12th fret.

So do I have everything right?

yeah, and small turns - you want to avoid having the rods at different tensions unless they need to be for some reason. On my original tobias i actually find it easier to use a wrench that fits the outside of the allen socket and turn that, but your rods may be a bit different.

Thanks man, I'll take a look at it tomorrow when I can get my hands on some tools.

I'm trying to do a truss rod adjustment on a friend's Tobias, but I need to go buy the appropriate wrench. Does anyone know what size wrench fits the rods?
