<p style=”text-align: center;”>Hello, I own Pitchfactor and this happened to me at a concert: I connected the aux switch and it didn’t work, disparate characters appeared on the display and after a while the pedal went back to the last preset I last played and wouldn’t turn it on or off. They didn’t work on the switch pedal. Knobs yes. I found that the cable from the aux switch has a broken contact. After changing the cable everything was the same. After about 1 hour, the pedal started working normally again. And now it works again. He fixed himself. The question is: Have you ever encountered such a defect? Can it reappear? Thank you for answer. Have a nice day… Pavel Johančík</p>
