I have one of those wonderful ukes and the stock strings are Orcas (or at least they used to be) which are very good quality for solid ukes, vintage or new. You'll find that tastes in uke strings are very personal. Some folks like Martin M600's and hate Fremont blacks and I have the opposite tastes. I haven't used Ken's new living water strings, but have tried quite a few brands on vintage and new koa and mahogany ukes and I prefer three brands, Fremont Blacks (medium), Worth Browns, and the Orcas that are on that ANueNue. I'm surprised there isn't more buzz about these ukes and on occasion they can be picked up used for great prices (saw one for $400). They are a fantastic and under-appreciated uke although I suspect many folks are scared off by the high price. Hmmm, not trying to hijack your thread, just thought that you might like more information, if you didn't already know it. cheers, g2
