Hey! Last week I bought a FBV MkII Express and I'm having trouble when I connect it to the POD XT (bean).
The pedal has been updated and calibrated. The POD has been updated too.
My problem is that when I connect everything, turn on the POD, the pedal turns on and suddenly both of them start to turn on and off until I turn off the POD power. I haven't found the solution, there´s an old topic but I tried everything the staff said and like the OP I couldn´t solve the problem.
