I just started playing around with my FX100. Its got a lot of capability, but that comes with complication. My current question is: does the volume/wah pedal function outside of all of the other effects, similar to the tone shaping and reverb controls on the face of the unit? If so, then why can you turn off the wah in the signal chain? Or, alternatively, is the volume/wah only active when you activate it via the remote app on your IOS or Android?
