  • I got the Spark today and noticed the same cracking farting sound, its more on humbuckers then single coils. Its not enjoyable, so im going to pack it and bring it back. No more positive grid for me.

  • I received one three days ago and had to return it back to Amazon. Felt stupid and fooled because i believed all those positive reviews. Now i bought a Blackstar amp, even more cheap and a good sound and more power
    Very good that you pay attention to the gimmick of the Mini Spark that did not spark.

  • Can someone recommend some speakers that would be much better than the original ones? Because it's great, but I find the speakers are just the weak link.

  • Hi I am about to place an order for this amp but now I’m not so sure after watching your video. So at what volume are you getting the cracking noise? Volume over half way? How loud is volume you are playing at? I just need it to be something that is loud enough for home practice. Thx

  • hey man, did you try to lower your guitar input in your patch settings? it sounds like your high input might be causing this cracking which is in fact a very regular thing with digital inputs. since this device simply a digital input with built-in speakers, maybe this could help your situation.
