plugging it into things
Every jack, what it is for, and the two or three that cause most cabling trouble.
the one thing
For a mono rig, always use the LEFT/MONO jack of a pair. Using the right one on its own gives you half your effects and a thin sound.

Your main instrument input, on the FRONT panel.
- Worth knowing
- The front placement suits plugging in at the rack. It is awkward if your rack sits behind you with every cable hidden. It has a switchable pad and selectable impedance, the same as the Floor.
the mono rule
Outputs come in stereo pairs, and only the left jack of a pair carries a summed mono signal. One cable from the right jack gives you one side of a stereo image: quieter, thinner, and missing anything panned away from it.
It does not sound like a cabling fault. It sounds like a bad device, so check this jack first.
