This is probably a really stupid question but, I've been looking for those six inch rulers with 1/64'' increments and I just can't find them. Now, I'm not trying to spend forty dollars to have some professional fix my guitar when I could do it myself with a lot more patience. The problem is is that I've found everything else that I need (polish, feeler gagues, etc.) but I cannot locate this ruler. Any help or suggestions will be greatly appreciated and thank for taking the time to help out a feller basser.
