I've been having a theremini for 2-3 months, already, but for the las 3 weeks, there's a problem with the volume antenna, as when I calibrate it, I realize there is only to positions: volume and no volume, and I can't establish the volume to work properly.
I have tried recalibrating, changing presets, etc., but nothing seems to work. Anyone knows what might be the problem, and/or how to solve it?
