The Mission Engineering EP1-L6 is an expression pedal made by Mission Engineering, designed for players using Line 6 gear. It is compatible with most Line 6 pedals that support an expression connection, and what it controls depends on the pedal it is paired with: volume, wah, pitch, tempo, or the wet/dry mix of your effect1.
What it does
An expression pedal has no sound of its own: it is a controller you connect to another pedal or unit, and it moves a parameter as you rock the treadle. With the EP1-L6, the target depends on the Line 6 pedal it is plugged into. Guitar Chalk's reviewer, Bobby Kittleberger, lists the possibilities:
The exact functionality also depends on the firmware of the paired pedal, so two Line 6 units can respond differently to the same pedal1.
Kittleberger tested it with his old Line 6 DL4 delay, with no firmware involved, and reported that he was able to tweak volume, mix, and delay tempo, though the DL4 offered no wah control1.
On construction, his verdict was direct:
"The EP1-L6 is built like a rock and is compatible with most Line 6 pedals that support an expression connection1."
Bobby Kittleberger, Guitar Chalk1
Overall, he found that it "nails the construction side, and adds a lot of versatility if you're working with Line 6 pedals"1. At the time of publishing that review, in October 2024, the EP1-L6 was selling for about $140 new1.
Mission Engineering makes a range of other expression pedals, including the EP-1, the SP1-L6H for the Line 6 Helix Rack, and the SP-H9 for the Eventide H91.
