Thanks very much for your time guys I know you all have your owns stuff to worry about. It's good to be able to come here and chat with people who have been down the road before you and are willing to give up some of their time to help other people.
The pots I've used are 2 x 500k Alpha. I've used 1 x 500k tone pot with a 0.47 400v Sprague (1 inch orange type)
I was thinking maybe some of this bright tone was coming from the bone nut, the hard frets and the ebony fingerboard. Maybe it would be wise to play about with some different pots and caps before I change the pickups
