I am using the FBV 3 Floorboard with a Firehawk 1500 Stage Amp. I have tried everything and I still am not able to erase the recorded loop, by hitting or holding any button on the FBV 3 a big dissapointment . I don't know if this may be caused by a default control setting that you must access through the FBV software controller via PC or Mac, and set it a certain way to work , this is just an idea that I came up with I have not yet checked it. I don't believe LINE 6 would be selling a brand new pedal FBV 3 , when it does not function as it should ...LINE 6 has been presented a support ticket on this issue but I have not yet heard back from them. I have thoroughly read through everything on the internet and found nothing that works. It is true that the looper function works on the Firehawk FX Floorboard as it should but it still does not work using the FBV 3 with the Firehawk 1500 Stage Amp.
