Yup. They're excellent.
If you do a forum search you'll find a handful of excellent reviews, many with sound samples.
Highly recommended.
everything everyone has already said is true. I've changed all my ukes to them... from soprano to tenor. The only set I wasn't happy with was the standard 6 string set. I ended up using part of the linear and standard to make my KA6 uke happy. Dirk was great when I told him of the trouble I had the the first standard set and explained why they set them up the way they did. He did all he could to keep me happy. I 'm a very happy customer.
