I just got my Axe fx 3 and love it, but have a quick question that's probably been asked many times. I'm wanting to hook my stereo pedalboard to the axe. I looked at page 31 and still having issues. I know guitar goes in the instrument in spot. My first pedal should go to the input 3L spot, correct. Then my reverb pedal has a L and R output and that's where I'm getting lost. How do I hook these up to get stereo. I know one output of the reverb should go to output 3L, but not sure where the other cable goes.
