The FBV 3 from Line 6 facilitates the hands-free operation of any compatible Line 6 amplifier or POD, giving you 13 footswitches and one expression pedal for this express purpose. The footswitches—which have been constructed from steel to ensure durability—offer different ways of controlling your apposite Line 6 device.
Two footswitches allow you to cycle through pre-programmed user banks with the tap of your toe, while four switches allow you to select among four channels within any selected bank; with these controls, you can easily change timbres for different parts of your song/arrangement. Furthermore, four user-assignable footswitches are also provided, which can be set to toggle various parameters of any effect called up by the FBV 3. A function and tap-tempo switch round out the panoply of footswitches, the former allowing you to enter Live Edit mode, the latter providing tap-tempo over delay and modulation effects. The tap button also triggers an onboard chromatic tuner and facilitates the exiting of menus in Live Edit mode.
In addition to the switches, the FBV 3 also includes an expression pedal for wah or volume control. A second 1/4" input can be paired with another expression pedal. This jack is specifically useful when used with the Line 6 EX-1, available separately. An LED screen displays a readout of your current preset and bank; it also serves as your interface whenever your tune your instrument. Multi-color LEDs on five of the footswitches coordinate with selected presets to help you keep track of all active timbres and effects.
 
The pedal draws both power and connection from connection to your POD/amp, doing so via the FBV 3's CAT-5 cable. Using the USB jack, you can control compatible software on any Mac or Windows computer, back up/store presets, and load sounds off your computer to boot.
