The Bigsby is only a tremolo, so unless you also install a roller type bridge, and a locking nut or locking tuning machines, your guitar will [u]not[/u] stay in tune under that kind of attack.

[QUOTE=cayotic727]and second will i be sacrificing anything by having one installed (alternate tunings, the tone i can get with a hard tail bridge.....)?

The trem bar position will move up or down a bit depending on how the string tension changes when you change the tuning. The tone won't be affected much by the trem, but if you have to change the bridge to a roller type, you are likely to lose some of the presence and thickness.
