I recently got the SSC pedal on my 255ext. Its definetly a nice pedal, but the main difference is that you get less range on the SSC pedal. Meaning because of the different resistor you have to be really easy with the pedal or you get more amperage than you want. While the original pedal that came with the unit has more range and travel. What i really like about the SSC pedal is that its just bigger in size and more stable, meaning it doesn't move around like the Everlast one. If they could somehow get more travel like the everlast pedal and make it more stable like the SSC, you would have the perfect pedal. But you get used to it. Was it worth it to get the SSC? I think so, but they both have their benefits. The everlast pedal is actually not bad at all. Hope that was helpful
