Thanks! So, if I have a standard ep-1, the pedal is always ‘on’ and just adjusts the signal, but the sp-1 with switch allows me to turn ‘off’ (if that makes sense)? So if I plan to use my fc-12 for ‘switching’ -between- blocks, I don’t need the switch (though it would in effect give me an extra on/off button), but having the switch could turn on/off say the Wah if I wanted, or I could get an ep-1 with spring and set to auto engage for the Wah? In other words more options with sp-1 but for my purposes not absolutely necessary but maybe nice to have? My last question then is if using to turn on/off wah if don’t use auto engage, or even just using the switch for something else, what jacks on the axe am I using? Is it 2 expression jacks and the switch is just toggling between the two? Sorry if I’m being dense.....
