I bought the Vintage pack.  On my HD500X I now have the following amps displayed after "Flip Top": 
  
Small Tweed 
Jazz Rivet 
Mandarin 80 
A30 Fawn Brt 
A30 Fawn Nml 
Black Panel Pete 
The next one listed is "BF Double Nrm Pre" 
  
However in the Edit program on my computer, "Acoustic" is listed right after "Black Panel Pete", but when I select it, my HD500X gets "Hiway 100 Pre".
