HX One
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.
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.
Controls and footswitches
Every control on an interactive top panel, including FLUX and the press-and-turn that makes the effect knob usable.
Inputs and outputs
Every jack across three faces, the loop hiding in the right-hand pair, and the only HX power supply that fits a normal board.
Specifications
The numbers that answer a question — starting with “one”.
What every model really is
Line 6's own decoder for the HX library. The amps are not on this device; the effects are.
Rig setup
In front, in the loop, four-cable, or under MIDI control.
Questions and answers
Straight answers to the things people actually ask.
Troubleshooting
Symptom, cause, fix — including what is documented behaviour rather than a fault.
