Ah , PCB is the Printed Circuit Board inside the pedal . Components are soldered to tracks on the board , and with the RAT , it ' s sometimes the case that one of those tracks near the footswitch is broken , and so doesn ' t conduct electricity as it should . Hope that helps ! <| sep |> That is one hilariously miserable scenario <| sep |> And it harms millions in the gap . Helping many at the expense of many is not an equitable system and people raged against it . <| sep |> Please don ' t spend 1300 crystals on banshee evo food , they sell 3 random gleams for 600 every month and getting 600 per month is about ~ 18 10 pulls . If you are a whale who can afford this , a single banshee fodder for the price of almost 7 gleams is ridiculous .
