I finally ordered my Sx jazz, and after reading tat the electronics are inferior, I went on bestbassgear, and found that they only sell 250k "volume" pots. 1. I want a 500k pot for the neck pup, anyone know where I could get one? 2. I also was wondering if those Volume pots can be used for the tone. 3. Should I use the more bass filled 250ks or the trebley 500ks for the bridge Pup?
