Line6 HX One Multieffetti Chitarra

HX One Compact Stereo Multieffect Pedal

Designed for guitarists who require professional-grade effects in a minimal footprint, the Line 6 HX One brings the Helix processor ecosystem into a single-pedal format. HX Modeling captures the nuances of analog effects by analyzing their individual components, resulting in lifelike recreations of germanium fuzz, bucket-brigade delays, and other circuits resistant to standard digital modeling. You’ll see the active effect and its three main parameters on the OLED display, while the Effect knob provides fast access to a library grouped by color-coded categories: orange for drive, yellow for dynamics, green for delay, blue for modulation. Its ultra-compact enclosure ensures it fits easily on nearly any pedalboard.

Flux Controller and Adjustable Input Impedance

What sets this pedal apart is the Flux Controller—a footswitch-activated parameter automation system capable of ramping multiple effect parameters at once with user-defined curves and timing. Before a chorus, for example, a delay’s feedback and mix may swell gradually over four beats, then drop instantly on the downbeat. The adjustable input impedance lets you compensate for pickups of different strengths, directly influencing both feel and tone at the input.

Effects Library and Processing Architecture

Drawing from the entire Helix effects ecosystem, each preset stores a single effect with in-depth parameter control across multiple display pages.

• Effects Count: 250+ algorithms — includes drives, dynamics, modulation, delays, reverbs, pitch, and filters from the HX family
• Users benefit from 128 onboard presets, all managed via the free HX One Librarian desktop application using USB-C connectivity.
• Looper — 60 s mono or 30 s stereo recording, plus shuffle mode for granular loop manipulation

MIDI Integration and External Control Options

Enjoy full MIDI implementation, enabling the pedal to receive program changes, continuous controller messages, and MIDI clock from external loop switchers or controllers. Side-panel MIDI In and Out/Thru connectors keep the footswitch area clear for performance access.

• MIDI: In, Out/Thru — handles program change, CC, and clock sync for tempo-based effects
• Expression / Footswitch: TS input — accepts a single expression pedal or two assignable external footswitches
• Stereo 6.3 mm TS jacks (L/Mono and Right) allow integration using the four-cable method with amplifier effect loops.

Bypass Modes and Power Requirements

Musicians can select between True Bypass, routing the analog signal directly from input to output, and Buffered DSP Bypass, which maintains signal quality over longer cable runs. External DC power is required; battery operation is not supported.

• Bypass Options: True / Buffered DSP — selectable per preset in the Settings menu
• Power: 9 V DC, 500 mA, center-negative 2.1 mm — compatible with most third-party pedalboard power supplies
• This pedal is designed for permanent pedalboard installation and does not operate on batteries.
