Unleash the full power of your Line 6 amp or POD and get hands-free control over your presets, tap-tempo your time based effects, activate the chromatic tuners, and enjoy one of the best wah-wah and volume controllers you’ll find. It’s built for many years of road use but small enough to fit into a briefcase. It also controls the 14-second Quick Loop on most Spider amps. Easily toggle the rocker pedal between volume and wah (with associated LED indicator) via a toe switch. Easy-to-read LCD shows tap tempo, active channel and chromatic tuner (when activated). FBV Control software allows unlimited mapping of FBV controls via USB and connects via RJ-45 cable or USB. This unit is self-powered and includes a very long stage cable to run from the front of the stage to your backline. Barely used and includes manual and other docs, as well as original box. Full details and software updates are available here, at Line 6’s site. If you use your Line 6 gear live, you need this unit. $69. If you want a complete set up, get the FBV plus a nice POD X3 and case, all for $329.
