I am having the same issue, how should I hook up the fx100 to my amplifi 150, I have both units connected bluetooth to my ipad, Is that good or bad, I can't seem to get any tone I like. Should I be going into the pedals (Amp Out) or the Stero (L), which controls are the master when tweeking, the amp, pedal or the ipad.... It's reaaking me out.... almost ready to take it back to the store. Please advise.
