I think a Bigsby is like a lot of other "trem" systems in that they work great when new and fresh out of the box and then start to exhibit problems as time goes on due to mechanical wear.

The only system I've used that worked over the long haul has been a Floyd but I got so tired of all the work involved with simple sting changes.

I have Parker NiteFly guitars and even they start to go down hill over time such that you just don't feel like using the wang bar ....now they're all locked down to work as hardtails.

I wouldn't say a Bigsby is a "bad" unit but I have seen more than a few guys use them during a song and after a couple of excessive bends their guitars were in Mystery Tuning so they go from playing a pop tune to an avant garde exploration of the Dipsolydian mode...much to the chagrin of the rest of the band. ;)

The one system that I have not tried that I suspect would be good is the Steinberger.
