I purchased an AMPLIFi 150 and am looking into a foot controller. Are there advantages to using the FBV Mkii short board over the FBV Express? Will the FBV allow me to store and recall more presets than the amps onboard 4? For instance saving the onboard 4 to a memory location in the pedal, then changing the onboard 4 with my iOS device and save them to a different memory location on the FBV so I can recall more presets with the FBV?
