After looking for two years, I have finally acquired a Kay bass. It's a 1951 M-1. She had been played at many outdoor bluegrass festivals, and has the "character marks" to show for it, but structurally, the bass is in great shape. There are no cracks (or repaired cracks), and the neck has apparently has never had to be repaired. It needs a fingerboard dressing, and I'll have a luthier take a good luck at the setup, but I couldn't be happier. Here's a photo. By the way, I had a Cremona until I found this bass. I know a lot of people on this forum hate them, but it served its purpose of helping me get started with an upright. Of course, now I can really appreciate having a good bass!
