HX Stomp
A pedal-sized HX processor with the full Line 6 model library, three footswitches and eight block positions. It is designed to be dropped into a board you already have — as an effects unit, as the amp at the end of a chain, or wrapped around an amp's loop in a four-cable rig.
If yours has eight footswitches it is an HX Stomp XL. If it has no amp models at all it is an HX Effects. Both are different boxes with different manuals.
The pages that exist nowhere else
What every model really is
All 440 amps, cabs and effects decoded from Line 6's own list. The same library as a full Helix.
Blocks, paths and DSP
Eight positions and how to spend them. What costs double, what collapses into one, and what to drop first.
Troubleshooting
Symptom, cause, fix — including the several entries that turn out to be documented behaviour rather than faults.
Controls and footswitches
Every control on an interactive top panel — two knobs doing six jobs, and the save gesture that isn't a button.
Inputs and outputs
Every jack across all three faces, the 3-amp power supply trap, and the aux input hiding in the effects loop.
Specifications
The numbers that answer a question — eight blocks, three snapshots, three amps of current.
What every model really is
All 440 amps, cabs and effects decoded from Line 6's own list. The same library as a full Helix.
Levels
Two settings decide whether it sounds like the demo or sounds broken. Both live in a menu, and neither is a tone control.
Cabs and IRs
What an impulse response is, how to load one, and why a downloaded preset can load fine and still play the wrong cabinet.
Blocks, paths and DSP
Eight positions and how to spend them. What costs double, what collapses into one, and what to drop first.
Rig setup
Effects pedal, four-cable, direct, bass or interface — the cabling and the cab block state for each.
Snapshots and modes
Four footswitch modes on three switches, three snapshots, and which layer a change belongs on.
MIDI
What a controller can actually reach, the three messages that recall a sound, and the trick that lets one preset serve several songs.
Questions and answers
Straight answers to the things people actually ask, in a sentence or two each.
Troubleshooting
Symptom, cause, fix — including the several entries that turn out to be documented behaviour rather than faults.
Firmware and backups
What an update changes, what it leaves alone, and the one-minute backup that means it never costs you anything.
