Plugging it into things

Every jack, what it is for, and the two or three that regularly cost people an evening.

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.

The jacks

Guitar, bass or synth. For a mono instrument, use L/MONO.

The input has a programmable impedance circuit, the same as a full Helix. If a guitar sounds harsh, that is the control to look for, in Global Settings.

The mono rule

Outputs come in stereo pairs, and only the left jack of a pair carries a summed mono signal. If you take one cable from the right jack, you get one side of a stereo image: quieter, thinner, and missing anything that was panned away from it.

This catches more people than any other cabling mistake, and it does not look like a mistake — it looks like the device sounds bad.
