I have a Spider V 30 amp, and now I have bought an FBV 3 foot controller, too. I notice that the FUNCTION button on the FBV 3 does absolutely nothing, and I wonder whether it should. I realize that it is intended to control the looper, which isn't there on the V 30 and the V 20 amps. Am I right that it should not do anything with my setup?!? A related question: I would love to have a looper added to my setup. Are there any recommendations out there? Thanks, Peter (from Denmark)
