Just got a new Ibanez SR 505 today. So far I have zero complaints and I really couldn't be happier with it. I have 2 questions though. 1) What do I use on the finish? It's wood, maybe oiled? I used to own a Warwick which required the wax polishing every so often. Should I use something like that, or would tung oil be better, or something else entirely? 2) There is a small knot in the wood on the back of the neck. It doesn't bother me at all and is sanded smooth as a baby's butt, however because of where it is located I am worried about the neck stability. Could this cause weakness or bowing in the neck as the bass ages? It's like a 5 piece neck, and the knot is only on one strip of wood. (obviously) Thanks, and anyone looking for a 5 string at a great price should check this baby out!
