trouble with wah

    I've tried different wahs with a Boss FV 500 H and a stereo cable in Expression slot 1, but none of them have a smooth transition from low to high. In the middle of the pedal there's a very quick small wah audible and that's it. No good! Anyone for how to get that low to high wah al the way? I need it for the second solopart of Guns and Roses Sweet child o' mine

    I don't know if the boss pedal can work propper with the kpa. What I can read in the boss manual you have to set two points ( high and low volume) at the pedal itself. Also and this is for every expr. pedal, you have to use a trs cable.


    Try to connect and set high and low at the pedal. Use the calibration in the pedalsettings of the kpa.
    Dont know if two calibrations will work together. I only use pedals without a calibrationfunction on the pedal itself like the mission kp1 gn pedal or the moog ep1 pedal.


    Good luck
