So basically you're paying for that nice case.
In addition to the book, you get:
1. Signed and numbered by Geddy
2. A "customized slipcase"
3. A "silver tolex briefcase ("reminiscent of certain guitar cases," and which is presumably suitable for nothing other than storing the book)
4. Behind the scenes mini-booklet
5. Two guitar picks
6. A signed photo of Geddy
7. An R40 set list that includes which bass Geddy played for each song
8. A "vintage Fender hang tag reproduction"
9. A set of bass strings
10. A guitar polishing cloth
11. An extra "standard edition" of the book because "some collectors will not want to break the shrinkwrap on their Ultra Limited Edition"
Some of it's cool; some of it's a little odd (a set of strings and a polishing cloth???). For me, the only things I'd be willing to pay extra for would be Geddy's signature and the behind the scenes mini-booklet. The "Luxe" edition has those things (plus a "custom fabric book bag" and the picks) for $450, but that's way too much for me to consider spending. I'm find with the "standard edition" for $60 (or whatever it's going for on Amazon at the moment).
Sorry, but who would want a mug with "Geddy Lee's Big Beautiful Book of Bass" written on it?
The guy two offices down from me.
