In summary, my impression of the Fender American Deluxe Strat is that it is the GTi version. It's like the sport model that's had some extra tuning done under the hood.
With limited tools and expertise I had to resort to the frightening prospect of partial destruction to get the neck off; I didn't want to just leave the guitar as it was because I would inevitably need to take the neck off at some point anyway.
It measures 46cm x 27cm x 20cm (11" x 10.5" x 8"), contains two 8", high-power Celestion drivers, it can handle 300 watts and weighs just under 7.5kg (16.5lbs).
