I've gotten a second set of Bona's in a trade-and dropped them in my Tak LP. Love the sound-but the gold/nickel battle is a little hard on the eyes. I might just throw on a nickel part or two I have laying around. Not a huge fan off all that gold anyway. But-I was wondering what the bobbin color is on these. The cover looks great, so I'll probably just leave it, but does anyone know if they are zebra or double black under the cover?
