First of all, I know how to adjust a normal truss rod. Please don't give me the "take it to a tech" lecture. I know the dangers. Secondly, When I took off the truss rod cover on the bass, it only had one place to put the allen wrench in, but I can plainly see the other rod. I thought maybe I need to adjust it from the other side, so I took off the neck and there is no opening or anything on the other side, except for a 5th smaller hole at the bottom where the neck screws in, but I can't tell what's there. So I have no idea what to do. EDIT: After some digging, I found that it looks like a Stew Mac Hotrod truss rod...? So I guess adjusting it does it to both rods at the same time?
