I've installed the Element in a several guitars: a 70s Guild Dreadnought, a late 90's Taylor and a recent Santa Cruz 000. It sounds great, but it's important to get the saddle angle right! I mis-calculated on my 000 and had a very uneven response across the the strings. Once I got the angle right, all was fine. Great sounding US - probably the best I've used.
Easy to install and sounds great, especially in a 12 string.
