Which one has the best classic Fenderish sound? i can't try any of the higher models because none of the stores has it in my country. The 57 twin-amp suppose to be amazing, but is doesn't have reverb, and Fender+reverb = MUST! The Vibro-king suppose to have the best reverb, but it's ss rectifire, and i'm a sucker for tube rectifire. so what d'ya say? thanks.
