I have an NF-1 with the momentary LED & I've noticed that if I step on it slowly, the light flashes but the pedal doesn't actually switch states. If I give it a standard quick stomp, it works fine. I don't remember this issue with the momentary LED CS-1 I had. Do any of you that have these momentary pedals notice the same behavior from yours?
I believe my SG-1 acts that way, which was rather disturbing at first, until I realized I can get the same if not better sounds from my Ernie Ball Volume pedal, and put the SG-1 away for safe collector keeping.
