So, the white pickguard and white knobs on my Fender sunburst p-bass are beginning to be a bit of an eyesore. So I'm going to get a black pickguard and chrome knobs. My questions are: 1. Should I go for aftermarket or genuine Fender parts? I've had bad experiences with pickguards before, so I want to minimize the risk. 2. Press-on or split-shaft knobs? 3. This is a little harder and separate from my p-bass questions, what is the resistence of stock Fender pots? Eventually I'm going to replace the pots on my jazz bass with new ones, since the stock pots feel loose and flimsy to me. Any input on this? Thanks all.
