Just got mine in, and couldn't be more impressed! You'd be hard pressed to find a nicer guy than Andy, or a better pot than those that he makes. Unlike some ceramics, his plays beautifully right out of the box, and it has a great sound. Rolls over easily, plays softly as well as it does loud and has a great back end rasp.
There are a ton of fantastics people on here that make some incredible calls, and Mr. Kaiser ranks up there with the best of 'em.
It'll be in the vest come March!
