Mission Engineering SP1-L6H-BK

This expression pedal is specifically designed for use with the Line 6 Helix units.

I have the rack version of the Helix and the separate foot controller. Unlike the floor version of the Helix, the separate floor controller does not have an expression pedal.

While many other pedals work with the Helix, the Mission L6H allows both treadle and button control. It connects to the Helix floor controller or to the main rack with 2 standard mono TS cables. 1 jack deals with the treadle and the other deals with the toe switch.

The amount of control it gives to the Helix is staggering. It can be just a volume control. Or pressing the toe down can activate a wah, turn on a drive pedal and change the amp model in use. It can be mapped to drive levels within a pedal too, or change reverb mix, or the mid control on an amp.

The build quality is excellent. The treadle is nicely weighted and does not squeak!

To get even more out of the Helix needs a full midi controller. I don't need that and the Mission L6H gives me all the control I need.

Excellent well built product!

When I decided on my Helix Rack, I wanted to add an expression pedal along with the floor controller. This looked like the most promising choice, and I'm perfectly satisfied.

- The range of motion is in the Goldilocks zone; not too much, not too little. Just right.
- The pot functions fine without any scratchiness or big jumps in operation, whether used as a wah or volume pedal.
- While it was initially quite stiff out of the box, it was pretty simple to adjust the tension to suit me.
- The build quality is set to "tank". You could take a running jump at this on a stage and it would just say "Again! Again!"

The only issue I had was that after adjusting the tension, the toe switch wasn't quite activating, but some fiddling with the included tools and accessory pads fixed that after a few minutes.

Overall, highly recommended. I'll probably grab another (maybe two for separate wah and volume) for use with my AxeFX.

I currently have 2 of these -They are very good pedals and play very nicely with my Helix Rack setup. They're quite heavy despite the reasonably small footprint. Certainly very robust.
These things are built to last, although of course that's reflected in their price!

I use a volume pedal a lot whilst playing, and to me these pedals can feel quite short throw and slack. Thankfully it's easy to stiffen the action and alter the calibration if needed. Once set up, the pedal holds it's feel well and the adjustment mechanism is suitably robust.

The housings themselves are quite clunky when the pedal is in use. At most normal playing volumes this is of no concern at all, but for some scenarios such as a "live in the studio with headphone monitoring" situation where bleed can be an issue, some damping of the base, treadle end stops, and switch tip is necessary. I used a bit of old carpet to cut some base plates and a few thin felt washers - much improved.
