I would say this is pretty good when you start playing, but after a while, I could feel some things start to deteriorate.
To start, after setting it up, it can hold a guitar in tune for a fair amount of time, though any crazy whammy stuff can throw it out of tune. It could be that I am not that great at setting it up yet, or the hardware has started to go through some wear.
It still sounds great, though if your playing style includes a lot of whammy bar stuff, invest in a guitar with a better bridge.
