Hello, This is my second self would pickup. The first one really sucked, but this one is a lot better. I'll be using this on my ash/bubinga bass. Show below is one of the coils, there are two of these to form a humbucker. Covers will be made to match the body (bubinga). For those of you with keen eyes, yes, the bobbin is made from lollypop sticks. They were dipped in minwax wood hardener to make them a little more 'stable'. Magnets are alnico 5 and as you can see from the picture, still needs leveling.
