Hi. One mans' flowers are another mans weeds. I own a P7 with a V7 on the way. I ordered 10 concentric black knob sets from ebay from a seller selling them cheaper in bulk. The same with the individual knobs - I found a seller again selling in bulk - multiples - 12 of them. I will use the rest of them on other basses I have or in the future (the V7), or will sell them to my friends.. The total amount was higher, but the cost of those knobs I put on my P7 came out to under $15. I am sure those sellers are still on ebay selling multiples cheaper. I only ordered them about 3 weeks ago. They are not fancy ones but look nice to me, They have a nice shiny black coating and a good gripping surface. There was a plastic sleeve that the control shaft fits into that easily falls out on some of them, but once you tighten the set screw, all is fine. I was surprised to find set screw knobs that cheap and had reservations about what I would get, but all went well in the end. I like them. They are about the same height as the stock knobs, but wider (and SHINY). I build guitars and basses as a hobby, so I think in multiples to save money when ordering online especially.
