The factory presets need to be loaded into the user preset locations.

The FBV2 just pages through the 4 presets on the amp (left or right)

The FBV Express has 4 buttons, to select the A, B, C or D presets in the current User preset bank

The FBV Shortboard lets you select the A, B, C or D presets and change the user bank, too, but you still need to load the factory presets into the user preset locations.
