Denver's Hard Rock Cafe on the 16th Street Mall just went through a major remodel and got a new collection of nearly 200 pieces of memorabilia including a couple of Rush items courtesy Alex Lifeson. From Denver Westword:

...In the front window there's Rush guitarist Alex Lifeson's monstrous amplifier (one of three he used during the 2010 Time Machine tour). It weighs 460 pounds and took six people to move. Lifeson's Gibson Howard Roberts acoustic guitar is on the second floor. ...

The article also includes photos of both Alex's amp and guitar as seen here.
