There's a setting screw in the pedal that can be ajusted. There's a fairly recent thread on how to sort out different issues with these pedals. I have slight trouble with internet connection today and can't search it up atm, but the major part can be found on archaic arcane's blog too. I have two old button type bakelite controllers I'm happy with, I have developed a feel for them and are keeping them. If you want to keep the original they can be serviced. You can also easily replace it with a new basic foot controler if you want to. The newer ones have better speed control.
