Hey guys, so a few months ago I bought a variax 700 and the model selector was not working correctly. I bought a new model selector knob hoping that would fix the issue but it has not. I tried calibrating the guitar but it will not calibrate using the method on the site...any suggestions? custom 1 through special work great, but the calibration gets stuck between chime/semi and then it kicks in again, however custom 2 does not work.
