Im using it with my TC Nova System, calibrates well enough to use it.
This is definitely a good expression pedal, very light, smooth action, big enough for my foot (11H), and a liberal price comparing to other pedals on market. After using a small AMT expression pedal for about a year, all i can say is that it just feels like a different level of quality. Recommend it by 100%. Planning to buy Dual version from EHX in my near future.
