I have often wondered which Garcia guitar Tribute is primarily based on, I presumed it to be Tiger but I am not sure. I also wondered what the scale of the neck is on the Tribute and if this is the same scale as on Garcias Tiger guitar.
The Tribute is a 25.50 inch scale, the same as Tiger, Rosebud and Wolf I believe. Tribute is more like Rosebud, since Tiger is solid and much heavier than its hollow cousin, Rosebud (to the tune of about 2 pounds).
Dozin's (http://www.dozin.com/JersGuitars.asp%20target=_blank) website has some good information about Garcia's personal guitars.
