I thought the Edge Zero II w/ZPS was a really good setup, but it took a while to get used to it. I really liked the additional stability on bends, but it made it feel stiffer when using for subtle tremolo... Which is my main use for a floating bridge. In my opinion it has it's good a bad points and it really depends on how you use the trem on a regular basis. Best to try one out if possible to see how you get along with it.What's the difference between an Edge-Zero II and the same trem with the ZPS system? It seems to be some sort of device for tuning stability but does that make the trem feel or act any differently?
If I didn't like the ZPS system, can I easily remove it and just use conventional springs?
On another note... The Jiva10 is one of the few new models that really catches my eye! I've been eyeing the factory seconds on Rich's website for a couple of weeks now. I love the finish and all, especially the "Beaten Path" fret markers. Not a fan of the bridge pickup sound at all. Hard to justify the price... but I still want one! Wish I could special order an unfinished Jiva neck and build a guitar around it.
