Introduction
The Line 6 HX Stomp XL is an advanced amp and effects processor designed for guitarists and bassists seeking versatile tone shaping and performance control. It features the same HX modeling technology found in Line 6's flagship Helix products, offering a comprehensive collection of amplifiers, cabinets, and effects. With its expanded footswitch layout, the HX Stomp XL provides enhanced real-time control and flexibility for live performances and studio applications.
Setup Guide
Follow these steps to set up your HX Stomp XL for optimal performance:
- Power Connection: Connect the included 9V DC, 3A power supply to the "DC IN" port on the rear panel. Ensure the power outlet is stable.
- Instrument Connection: Connect your instrument (guitar or bass) to the "INPUT L/MONO" jack using a standard 1/4-inch instrument cable. For stereo input, connect a second instrument or stereo source to the "INPUT R" jack.
- Output Connection: Connect the "OUTPUT L/MONO" and "OUTPUT R" jacks to your amplifier, audio interface, or PA system. The outputs are switchable between line and instrument level, allowing for flexible integration into various setups.
- USB Connection: For computer connectivity, firmware updates, and using the HX Stomp XL as an audio interface, connect a USB cable from the "USB" port to your computer.
- MIDI Connections: Utilize the MIDI IN and OUT/THRU ports for external MIDI control or integration with other MIDI-compatible devices.
- Expression Pedal/Footswitch: For additional real-time control, connect up to two external footswitches or expression pedals to the "EXP 1/2" and "FS 1/2" jacks.

Operating Modes
The HX Stomp XL offers several operating modes to suit different performance and editing needs:
- Preset Mode: In this mode, the footswitches allow you to navigate through banks of four presets. This provides quick access to your saved sounds during a performance.
- Stomp Mode: Pressing the "MODE" footswitch enters Stomp Mode. Here, the footswitches are assigned to individual effects blocks within your current preset, allowing you to toggle them on/off. The color LCD screen displays the assigned blocks and their parameters, which can be edited directly using the knobs.
- Snapshot Mode: By pressing the Up and Down footswitches simultaneously, you can access Snapshot Mode. This mode allows you to store and recall up to four different variations of a single preset, enabling seamless transitions between different sounds or effects configurations without changing the entire preset.
- Pedal Edit Mode: This advanced mode allows you to edit the parameters of any amp or effect using only your feet. Hold down the "MODE" footswitch, then select a block and a parameter to adjust its value using the footswitches.
