I have a Hartke HA5500 in a rack and have added the Korg Pitchblack Pro rack tuner and a Line 6 G55 wireless. How do I link them. Obviously input of the head to the output of the tuner but then there are 2 inputs on the tuner to go to the Wireless which is mic level. So do I use Input 1 on the front. Or input 2 on the back which is line level, I would prefer to use input 2 so I don't have to come back to the front of the rack again. Does it make a difference which input I use?
