Hi! I use Spider v 240HC (2.05) with FBV express mk2 When I pick up master I hear frequent clicking sounds. The sounds clearly come from the expression pedal. If you change the position of the pedal, you can also hear accompanying sounds. I thought the pedal was defective. Connected it to Spider Jam - everything works fine. No otherworldly sounds at any volume level. Now I can’t figure out what to bring for repairs - нead or controller. Please help (
