I'm very taken with the Kinmans on a couple of friends' Strats and quite fancy them for my next project. However, they are rather pricey and I have also been considering Fender Noiseless units as an alternative as there seem to be a good few of them on eBay for a decent price. Am I right in thinking they are very similar in design and sound? I seem to remember one party taking the other to court a few years ago over some kind of patient infringement (can't remember which way it worked). Any thoughts, recommendations and suggestions would be appreciated.
