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.

INPUT L/MONO, RIGHT
TS / TRS, ¼″rear panel
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.
HX Stomp Cheat Sheet (Rev C)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.
