Warwick Truss Rod Direction
Trying to straighten out the neck on an extremely cantankerous 2002 Warwick Thumb BO 5 in Ovangkol.
When I bought the bass it had just a slim gap of relief which I was fine with at the time. That was in October; roll into winter, and the neck gets more relief. So I open up the truss rod cavity and put the wrench in, give it some gradually increasing force to the point where I wasn't comfortable pushing that hard: doesn't move.
So I take it to my nearest tech, he rants about how much he hates over-his-head, innovative German engineering, turns until we hear a massive creak (all the strings loosened I might add) and stops. Then he says the same comment you see on every Warwick related thread, "I think sometime back Warwick used a reverse truss-rod, but I don't know quite when." Gives it a turn the other direction, it begins to move until it gradually slows down and makes another creak. We quit after that. I didn't see any difference in the neck after all this, and by now it already had a huge amount of relief.
A few months go by and I decide I absolutely hate playing this bowed neck so I must do something about it. I start climate tempering it like an acoustic, leaving it in warm, humid weather with the strings off. During this process I learned that my truss rod had been maxed out in the clockwise direction and so I would turn it in the counter-clockwise direction until it would freeze up, then I'd let it sit overnight, and the next day it would keep turning until it froze up again (I assume this is the neck settling into place before the truss rod can freely move again).
So now that I worked out plenty of workspace in the truss rod, I have the bass in clamps with a 2x6 block on the 6th-14th fret wires. Question is, after all the truss rod turning I've been through with this bass, the neck has had such HUGE relief, and the strings have been off so frequently, I honestly still can't tell if the truss rod is normal or reverse.
If anyone has any information on this, or any similar experiences they would share, I would greatly appreciate it.
