I have a Dot Studio. Besides cosmetically, the differences between the ES-335, the Dot and the Dot Studio are:
ES-335 - mahogany neck, maple center block
Dot - maple neck, maple center block
Dot Studio - mahogany neck, mahogany center block
the pickups in this guitar are pretty good I think. they're the Alnico II. I think there is some kind of maple laminate on the this guitar and gives it a real snap.
the bigsby style vibrato changed the tone quite a bit. it made it warmer and more midrangey.

the vibrato is this bigsby knockoff one that stewmac used to sell about a year ago. like a real bigsby it adds a considerable amount of weight to the guitar.
