Just got my first EHX pedal, the Mel9. I read somewhere there’s supposed to be two versions. If this is correct, how do I know which one I have?

Anyway, I’ve noticed the footswitch takes a much harder stomp than my other pedals, and seems to make quite a loud acoustic CLICK. Sounds like a huge hole puncher going through too much paper than it can handle. Is there a way in which I can alter it so it reacts to softer stomps, and doesn’t make so much racket that it distracts me?

Thanks.
