      Hey all,

      Issue: please have a listen to the two sound examples I uploaded. In most of the settings, especially when their seems to be some kind of gain/distortion involved, i have a very loud crackling background noise.

      Sound files on Soundcloud:
      Clean mode all the way to metal mode
      Test with VOL control on guitar

      I bought a Ibanez RG421 (2× Humbucker) and also played the first week on a mini Amplug (VOX) without issues. Guitar was working fine in store as well. I also tried plugging my western guitar, same issue.

      In one of the recordings, I turn the VOL knob of the guitar up and done and it effects the sound issue - as the Gain, Master or Output know on the Spark does as well. So clearly if I turn up the volume the sound issue is amplified as well.

      In the other, I switch from the clean mode all the way through the metal mode. You can here that it gets worse and worse.

      Lastly, the crackling sound is audible when I play / touch the strings only. And also endures around 3-5 seconds after I mute them. Then the background noise fades out and is gone... weird!

      Many others talk about a "hum" issue. I also saw videos of that. I believe I could have a different problem. Grounding the Spark with a laptop reduces the noise but only a small bit. It is still present.

      Do I need to return the Spark?

      Cheers!

        I would click the "contact support" along the top of the webpage and fill out a ticket. I don't know if PG monitors these forums regularly.

          So you confirm that this is not ok or based on me having settings wrong?

            This crackling noise is not normal. They must change the amp.

              It seem that it was an issue with a Powerline adapter which was connected to another socket in the same room. For now, as soon as I unplugged the adapter, the crackling sound went away. I will test further the next days.
