hello everyone, i own a line 6 amplifier red 50 w 1x12" bought in 2000. I would like to buy a footswitch, and i found a fb4 used on ebay, and a fbv4 brand new. does someone know if fbv4 is compatible with line 6 red amplifier? i would like to buy fbv4 because is new, instead fb4 is used! thank you very much!
