I am buying Casio PX330 and planing to upgrade my pedal, which is a box type, to a full-sized pedal. A lot of people got SP-30 but I am thinking about getting SP-20 because it is cheaper and I will be using mainly only the sustain pedal (and also I don't think the other two perform their function very well)
My question is this SP-20 has a half-dampered capability? I could not find this information in the Casio website.
