I too just got my FBV 3 last week and am having issues with my Spider Valve MKII 212. The board powers up and I have display, but seems very sluggish to respond (if it responds) to pedal presses. If I hold down the TAP button, it will not turn on the tuner (if I press the TUNER button on the amp it will come on). I pressed the BANK UP button 5-6 times before it would respond......for $249 this thing is a piece! Thinking of returning it to Zzounds. WTF Line 6?
