Which guitar in Red Rover?

[seteca]

LB said in Guitar One magazine:

...and we’re working on “Red Rover” today – it’s interesting to do live. We’ve got three guitar players running through this vibrato on/off thing, and the on/off is toed into a specific click. And we have to play to that click or the timing’s all off, so we’re working it all out and it’s pretty trippy.

So (unless the arrangement has changed since this June 2003 interview), it's the three musketeers playing in perfect synch.
