That's an AWESOME DNA.
I've seen this before on knobs. I ordered pink knobs strait from Ibanez for about 8.00$ a peace. They didn't match the
Dimarzio PUPS at all. So i did a little research. Apparently the original knobs are white, and then painted. Therefore, the colors are much more brighter than the plain factory "molded" colors. Sims customs has a set of Orange original knobs on his website for 49.99$ or something. There was a guy here locally that had a set of original pink knobs that i wanted to pick up for my FP but he wanted 120.00$ for the volume, tone and switch. So I passed on that.
Unfortunately the original knobs match Dimarzio PUPS so much better than the current Ibanez factory stuff that if I get another chance on an original set i just might pick them up. Some one could probably make a killing molding white knobs and painting them if they could get them to match correctly...
