These were on my Hanewinckel when bought many years ago. When I had Mr. H add a preamp to the bass, he said that these were not the original pups, but that they were good and didn't need replacing. A year ago, I replaced them with Barts for what seemed like a good reason at the time. Anyway, they work and sound great and are sitting around here. $30 for both shipped in the lower 48. I can send pix, but there are no exposed pole pieces on these pups.
