Multi-function Expression Pedal Tailor-made for Your Quad Cortex

As Mission Engineering's flagship pedal, the SP-1 set a new standard among expression pedals thanks to its seemingly limitless versatility and pro-quality construction ideal for life on the road. The SP1-ND introduces the SP-1's full-featured functionality to NeuralDSP's ultra-powerful Quad Cortex modeler and profiler, letting you control and manipulate a wide range of effects processors with expression inputs. By connecting the SP1-ND to the pair of expression inputs located on the Quad Cortex, you not only get instant access to silky-smooth expression at your feet, but the pedal's built-in toe switch also makes it a breeze to engage and disengage effects without the need for additional hardware — a level of detail Sweetwater guitarists thoroughly appreciate. Throw on a rubber pedal surface for slip-free operation and a metallic-grey finish that matches the Quad Cortex to a tee, and Mission Engineering's SP1-ND is just what you need to round out your digital rig.

Mission Engineering SP1-ND Quad Cortex Expression Pedal with Toe Switch Features:

  • Rugged and reliable expression pedal for use with the NeuralDSP Quad Cortex
  • Linear potentiometer offers perfect precision and a natural response
  • Controls expression input-equipped effects processors for modulation effects, delays, and more
  • Built-in toe switch toggles effects on/off in a flash
  • Rubber pedal surface for non-slip operation; metallic grey finish matches your Quad Cortex perfectly

Reviews

Amazing pedal
Prior to getting this pedal, I tried a few other petals out on the market. I've seen people complain that there's not enough resistance on this blah blah blah blah blah but reality is this pedal is amazing. It syncs with a quad cortex perfectly. There's not too much movement in a pedal like a lot of the other people that give us cheaper petals. So if you're used to using a typical wall pedal, this thing feels just like a typical wall pedal has been on the market for 50 years, it acts like one except everything about it feels a little bit higher quality from engaging the pedal to the way it sweeps through the potentiometer everything about it. It's just high-quality so for people that are complaining about the quality this pedal they haven't been playing guitar long enough and use enough wall pedals to realize what these things feel like for those of us that have come from the world of amps and paddle boards this thing feels exactly as we wanted to. This has the right amount of place. You're not having too much movement to try to get to sweep through the wall and it is also the perfect amount of movement for using it as volume or anything else you need to use it as. All in all this thing is superb.
Great expression pedal, does exactly what it needs to
A great expression pedal for the quad cortex with a nice smooth action, feels sturdy, great hardened exterior. Reminds me alot of my crybaby original or the expression pedal for the Dunlop Univibe UV1. If you're familiar with either of those products, expect a similar durability and build quality.
Built Well, Does its Job!

I have 2 Mission Engineering expression pedals on my board. They are built solid and work well. Smooth range of motion.

I just wish these were a little less expensive.
