Gypsy F Hole guitars are not archtop guitars. They do not sound the same at all. The difference in sound comes from the top, which is carved on an archtop, and pressed on an gypsy F-Hole guitar. Also, the bracing patterns are totally different. You can see below how the braces differenciate. 1 and 2 are gypsy F hole guitars, with ladder bracing, while 3,4 and 5 are archtop guitars.
