Hi there, I recently bought a SA Orbital Modulator via eBay (for $96--not bad), possibly from one of you. I like it well enough, though I haven't played around with it a lot yet, but what's bothersome is the VERY LOUD "click" when I turn the pedal off and on, for either preset button (switching between the presets doesn't do it). I have the SA Manta and that one didn't have this problem. Is this normal for this pedal? Does anyone know a trick to make it go away?
