Hi, So I recently got a POD HD500 and when I bring the volume pedal all the way down, some noise from the guitar still gets through. Quieter, but still audiable. So I followed this "volume pedal calibration" instruction shown below many many times, word per word. I even have a video of me doing this exact calibration process if anyone wants to see! But It still hasn't fixed it! Does anyone have any advice?? Thanks!

Hold the down the RIGHT ARROW button on the 4 Way Nav Pad while powering the unit on, until you see the “Test Mode” screen (Pedal Cal, etc.), and then proceed with the steps below:

1. If not already selected, use  on the 4 Way Nav Pad to select “Pedal Cal,” as shown above. 
2. Press the VIEW button. 
3. Set the pedal to the minimum “heel” position, then press the A footswitch to set a value for the Duty Cycle. You’ll see the value set to “100.” 
4. Set the pedal to the maximum “toe” position, then press the B footswitch to set a value for the Duty Cycle. Again, you’ll see the value set to “100,” as in step 3. 
5. Press the C footswitch to prepare for automatic selection of the Scaled Pedal Value and move the pedal from min. to max. You should see the Scaled Pedal Values read “0” at the heel position and “255” and the toe position. If you get values other than 0 and 255, power off and repeat these steps, starting at step 1. 
6. Press the D footswitch to save the settings. You’ll be returned to the Test Mode screen and the Pedal Cal item will show a “P” to indicated that the pedal calibration is complete! Power your device off and back on again to start using it.
