Lube my instrument?

[Rampant]

Just use graphite or nut sauce on the nut. The bigsby's moving parts run on delrin bushings which are effectively self lubricating. I'd only lube the roller bridge if it starts making squeaks or pings that you can hear through an amp. A drop of light oil on a toothpick applied to the roller axles would be the way to go here but use it sparingly and wipe up any excess. Don't get machine oil on the guitar's finish.

Thanks for that Mark.

Do you think my Ibanez copy of the Bigsby trem has got a self lubricating bush???
