Have 2 Ken Smith Burner, a deluxe and other Custom. are wonderful and are today with two great friends that lend me to use. Today I have a KSD proto 5, which I'm using to 2 years and never had to adjust the rod as the neck. Their KSD are fantastic and traded my Fender 5 for it due to the great sound of the B string due to scale out instead of 35 inches of 34. His idea of producing the bass guitar in China rather than their USA was due to low cost of labor? For this instrument, because of great quality, could receive the "label" "MADE IN USA". I wanted to know what circuit you use and if the pickups are made for you, KEN? There is the original replacement part eletronica if by chance one day a problem occurs? Sound that I love and I would always keep it original.
