What you actually bought
What this box is for, what it is not, and the one sentence that explains most of the confusion around it.

It is a whole guitar rig in one box — amps, speakers, microphones and effects, all modelled. Whether it sounds right depends almost entirely on what you plug it into.
The short version
A single-pedal HX device running one stereo effect at a time from Line 6's full effects library. No amp models and no signal chain to build — it is designed to sit on a board you already have, in place of the one pedal you keep swapping.
Is this the right guide?
If yours has six footswitches and scribble strips it is an HX Effects, which runs a whole chain at once. If it has amp models it is an HX Stomp.
The thing everyone gets wrong first
On a HX One, the question we see most is the right footswitch doing the wrong thing.
That switch is either tap tempo or FLUX. Press and hold it to toggle — red is tap, white is FLUX.
