Here's What Mission Enginering say about the Expression Pedal:

The Line 6 Helix Rack and Helix Rack Floor Controller feature expression toe switch jacks that allow you to switch effects on an off directly from the SP1-L6H expression pedal. You can now turn your wah, whammy or other effects, on and off without having to take your foot off the pedal.

The SP1-L6H works with the advanced features of the Helix Rack to provide extensive real time control of your rig. Use the pedal to vary multiple parameters simultaneously. The switch can toggle the pedal between different parameters, allowing you to use a single expression pedal for multiple effects. Integration with the Helix programming interface enables you to use the expression pedal to quickly cycle through menu options when making changes to presets on the fly.

Built with the same all metal construction and highest quality components that have made Mission pedals respected worldwide for their performance and reliability, the SP1-L6H features a non slip rubber pedal surface and resilient black finish to match the Helix.

Expression

Expression pedals allow real-time control over specific parameters on compatible guitar pedals, such as volume, delay time, modulation depth, or filter sweep. Used with an expression input, they let players shape effects dynamically with their foot, adding movement and performance control that cannot be achieved with fixed knob settings.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Wah

Wah refers to an expressive filter effect that sweeps through a range of frequencies, creating a vocal-like “wah” sound. Controlled in real time with a foot-operated treadle, it allows players to emphasise different parts of the frequency spectrum as they play. Wah pedals are commonly used for lead guitar, funk rhythm work, and expressive solos, responding closely to picking dynamics and foot movement.
