Tuner with pedal not working

    I have been using my Stage profiler for a number of years with no issues. I use an EV1 for volume and for the tuner. Lately I have had an issue with the pedal not working. Last night I could not get the tuner to work with the pedal. Everything is connected as usual…..using a TRS cable. Any suggestions on what to check/look for? Thanks

    I would recalibrate the pedal. Enter PEDAL settings, navigate to the PEDAL page corresponding to the socket the expression pedal is connected to, press Calibrate, and perform a complete sweep of the pedal. Only if the pedal reaches the value 0 in heel position, the Tuner will get activated.


    And make sure, that the option Tuner @ Volume 0 is selected in Tuner Mode.

    So I got to church this morning, plugged everything in....and my volume pedal no longer works. When I go to the rig page, the volume bar is all the way up. Can't make it change. This is so frustrating....I cannot figure out why it has stopped working. And this a brand new EV1..

    Have you tried any other function? E.g. assign a dual switch and module A to the tip and close sleeve against tip of the TRS jack with a paper clip. DDoes this switch module A on/off. Also try to press Calibrate.


    If that doesn't work, we have to conclude, that the PEDAL socket is broken.

    If the pedal 1 socket is the issue, then 3 has a problem as well. I switched over to 3 when I recalibrated the pedal. When I connected it again on Sunday morning, it would not work in pedal 3……I think it’s something more…

    Yes to both of those questions. And I just updated the firmware....same issue. I cannot calibrate the pedal, there is no response in Pedal 1 jack or Pedal 3 jack. It really seems like a software issue. One day it was working, the next day it doesn't. Really frustrating. Makes me seriously consider moving to a different platform........

    It cannot be a sofware problem, otherwise tons of people here would have the same issue. Can be only, setup, the exp.pedal itself or the jack inputs on the KPA.

    I (like a couple of thousand people here) have the same setup and never had a flaw in thousands of hours of use and at least 10 software updates.

    Again; Software is excluded

    If something is too complicated, then you need to learn it better

    This is no software issue.


    What kind of expression pedal are you using? Fractal offers an EV1, Boss offers a wireless EV1 ....


    If the pedal has a pot to adjust its range, make sure it's set to maximum.

    Just wanted to post an update....so this was totally my fault. Ended up being a bad TRS cable. It sort of worked which led me to believe that it was still good. Once I replaced it with a new one, all is good. Thanks to all of the people who replied. I truly appreciate all of the assistance available here...
