Line 6 Helix Stadium XL Floor

The Line 6 Helix Stadium XL Floor is a digital amp and effects processor, a floorboard that replaces an amplifier, a pedalboard and a rack of outboard gear in one unit. Line 6 calls it "the most comprehensive and integrated guitar processor ever created" by the company¹. It is the larger of the two Stadium floorboards, the successor generation to the Helix Floor released in 2015, announced ten years on², and it began shipping at the tail end of 2025³.

Under the hood is the new Agoura modeling engine with Helix effects, driving 134 amp models⁴ and a set of stage features that go well beyond guitar processing: 8-channel audio interfacing, Matrix cue mixers, and Showcase automation and playback engines⁵. Guitar.com's reviewer summed it up as "a multi-FX digital amp modeller, studio-quality audio-interface, modeller, DAW, with the facility to connect to stage lighting and live mixers"⁶.

What it does for a player

The Stadium XL Floor models amplifiers and effects and routes them anywhere a gig needs them: to a PA over balanced XLR/TRS outputs, to a computer over USB-C, or digitally over S/PDIF¹⁴. It has 2 variable impedance instrument inputs with 126+ dB dynamic range, a dedicated XLR mic preamp, and 4 stereo effects loops¹⁴. Line 6's Eric Klein described the Stadium family as offering "the best-sounding, most powerful, and most flexible processing Line 6 has ever offered"¹⁰.

The amp side uses the new Agoura modeling tech, with a Hype control on those amp models¹¹. Guitar World's Steve Sterlacci explained what Hype does: it is "designed to take the model slightly away from an accurate recreation" toward an idealised version of the real amp². Guitar.com's Richard Purvis put it another way:

The unit also gained profiling-style capture capability: a cloud-based cloning engine for making captures of your gear¹⁰, and Guitar.com notes recently added profiling capabilities¹⁰⁶. Firmware has kept moving since launch, with software version 1.2 adding phase 1 of Showcase².

The controls: touchscreen, scribble strips and footswitches

The centerpiece is a high-resolution 8-inch touchscreen, up from the six-and-a-bit inch screen of the original Helix, and now with touch control⁸¹². Around it sit 12 high-contrast OLED scribble strips, one per footswitch, an XL-only feature¹³, and eight mini encoders, two more than the original Helix had².

The footswitches are configurable: they can be set to control Presets or Snapshots, a combination of both, or run in Stomp Mode like a traditional pedalboard². Guitar.com's reviewer found the whole hardware package works with "some help from the many knobs and buttons plus the touch-sensitive footswitches" alongside the screen¹².

Power and connections

The Stadium XL Floor runs on an internal power supply fed by an IEC mains cable, the same approach as the original Helix, so there is no wall wart and no pedalboard power supply requirement¹². Connectivity is broad:

• MIDI in and out¹¹
• Bluetooth and Wi-Fi control¹
• S/PDIF in and out¹
• USB-C and USB-A¹¹
• Micro SD slot and Nexus link¹¹
• Balanced XLR/TRS outputs, USB-C 8-in/8-out 24-bit/96kHz audio interfacing⁴
• 2 variable impedance instrument inputs, 126+ dB dynamic range¹
• Dedicated XLR mic preamp and 4 stereo effects loops⁴

As an audio interface it carries 8 channels of 24-bit/96kHz audio over USB-C⁵, and the Matrix cue mixers and Showcase automation and playback engines let it serve as a stage hub rather than just a guitar processor⁵.

Stadium Floor vs Stadium XL Floor

The Helix Stadium Floor is the smaller sibling, available Winter 2025⁷ and shipping from February 2026⁷. The differences, per Line 6 and the press:

Sweetwater's demo noted the XL is roughly half an inch taller, half an inch deeper and 3 and a half inches wider than the Floor, and about 4 lb heavier¹⁵. Guitar.com's reviewer found the XL "slightly less monolithic in dimensions than the old Helix Floor"¹².

What reviewers said

Guitar World's Steve Sterlacci reviewed the Stadium XL Floor and concluded that "the Stadium XL Floor easily surpasses its predecessor and is a great choice for any working guitarist"². He called the eight-inch touchscreen "the star of the show," bright enough that he had no worries about it getting lost outdoors².

Guitar.com's Richard Purvis reviewed it in April 2026, praising the Agoura amp modeling and the touchscreen while noting the high price and complexity, and calling it "ridiculously powerful in terms of functionality"¹². MusicRadar's reviewer highlighted "a mountain of DSP, plenty of connectivity options, a built-in expression pedal"¹¹, and MusicRadar's October 2026 buying guide placed the Helix Stadium XL in its live-use category¹¹. Guitar World's multi-effects guide gives it four and a half stars overall¹⁶.

On Andertons' review video, the presenters noted one practical caveat: there is a split-second gap when switching between patches with the ABCD buttons, where the patch you are leaving stops before the next one starts¹³. The same video covers the effects side in depth, including a Timmy-style overdrive with gain, bass cut, treble cut, clipping and level, a Minotaur clone-style overdrive with gain, tone and level, an SD9-based Hedgehog distortion, and a Feedbacker effect that can re-trigger feedback on different pitches, an octave above, two octaves above, or two octaves and a fifth above¹³.
