As far as I can tell, the biggest issue with the pots is that Villex is using anti-log (reverse logarithmic) taper pots for 3 out of the 5 controls on the NVT harness. These are hard to find in the best of circumstances, especially with dimensions suitable for a bass guitar and resistance values appropriate for the needs of the NVT system. Plus, even though many of the pot manufacturers would be happy to make these to order, they require a large quantity to justify their investment. Unfortunately Villex does not have the resources of a large company such as EMG, who can order custom pots and other electronic parts with impunity.
I've found that linear pots work just about as well for my needs, but I can certainly understand Villex's desire to get things "just right" based on his specifications. In another bass with Villex classic pickups, have also used regular audio taper (logarithmic) pots wired backwards, but I'm not sure everyone would want their Villex basses to have backwards pots.
Regarding the website, I would also like to see more information about the newest product developments, but I can understand the constraints of time. If he has a limited amount of time and a bunch of orders to fulfil, I would probably agree that the maintenance of the website has a lower priority. I am working on some other projects now, but when I am finished I will offer my assistance to see if he would like some volunteer help for the website.
