Line 6 FBV Express MkII — a 4-channel foot controller built for Line 6 amps and PODs (Spider II/III/IV, Spider Valve, Vetta, Vetta II, Flextone III, HD-147, LowDown Bass amps, and more). Instantly recall amp channels via four steel footswitches, tap tempo for time-based effects, an onboard chromatic tuner, and a full-size toe-switchable Volume/Wah expression pedal. Self-powered through the connected locking cable — no separate power supply needed. Shows normal cosmetic wear from use (scuffed switches, some surface dust) but functions as expected. Includes the required locking RJ-45 cable — plug straight into a compatible Line 6 amp or POD, no extra shopping needed.
