Congratulations on your purchase of the Mission Line 
6 expression pedal. This product is designed to be 
intuitive to setup and operate, and to provide many 
years of trouble free service. However, we recommend 
that you take a few moments to read through this 
User Guide in order to get the best possible experience 
with your new pedal.

The Mission EP1-L6 and SP1-L6H are professional 
quality, all metal expression pedals designed for use 
with Line 6 products. Mission and Line 6 engineers 
collaborated on the development of these expression 
pedals to ensure perfect control of effects parameters 
such as volume, wah, and delays. 

The EP1-L6 is a single output expression pedal for 
use with Line 6 digital amplifiers, multi-effects and 
effects pedals. The SP1-L6H additionally features 
a toe switch, that when used with the Line 6 Helix 
Rack, supports switchable functions such as turning 
an effect on and off, and toggling between effects. 

Pow

 

These expression pedals are passive devices, and 
require no internal battery or external power source 
for expression control and switching.

The EP1-L6 uses a single ¼” TS phone plug output 
marked 

OUT1

 on the underside of the pedal. Connect 

OUT1

 to the pedal input on your compatible Line 6 

device using a ¼” instrument cable. 

OUT2

 is unused 

on this model and is blanked off. 

SP1-L6H

The SP1-L6H uses a two ¼” TS phone plug outputs 
marked 

OUT1

 and

 OUT2

 on the underside of the 

pedal. 

OUT1

 is the expression pedal output and 

OUT2

 is the switch output. Connect 

OUT1

input on the rear panel of the Helix Rack or Helix Rack 
Floor Controller using a ¼” instrument cable. Connect 

OUT2

 to the EXP TOE SWITCH input on the Helix 

Rack or Helix Rack Floor Controller. 

Expression pedals do not require an input. The 
input side of the pedal is blanked off.

ConfigurAtion

Your Line 6 device may require configuration to 
use the connected expression pedal, and to assign 
the pedal to the particular parameters you wish to 
control. Follow the instructions in the user guide for 
your Line 6 device to configure the expression pedal.

The tension of the rocker can be adjusted using the 
tension adjustment screw on the rear of the pedal 
between the rocker and the base. Use the hex key 
provided to tighten the adjustment screw until the 
pedal remains in place. It maybe necessary to adjust 
this screw every once in a while to compensate for 
use and environmental conditions such as very hot or 
cold weather, when the pedal has been stored for a 
long period, or after shipping. Replacement hex keys 
are available from Mission Engineering. The tension 
adjuster is not included if the optional spring load has 

been fitted.
The switch sensitivity on the SP1-L6H can be 
adjusted by lowering or raising the switch in the 
chassis. Use spacers and washers provided to lower 
the switch making it harder to press. Remove spacers 
and washers to raise the switch making it easier to 
press. When replacing the switch, be careful not to 
over tighten the lock nut and damage the switch.
Do not use the pedal without the supplied baseplate 
and feet installed. Attempting to screw the baseplate 
to the pedal without the rubber feet may result in 
damage to the chassis. For fixing to a pedal board, we 
recommend the Mission PR-1 Pedal Riser kit available 
at http://www.missionengineering.com
