all them have audible output except subass channel. So what about center? is it the mono output?, also what it's diference between using channels left/right or LeftSorround/RightSorround. Is there an audible diference?
This is because Heavier7Strings have solo/dual guitar mode. To allow users connect each of the dual guitars to different route, we provided 3 pairs of channels: one pair for both guitars, one pair for guitar 1, and one pair for guitar 2. Please refer to user manual for more detailed description.
