HELP! Spark Amp extreme hum!
-
I purchased this at the first half of June. It arrived just a week ago. When everything is plugged in and on I get nothing but a really loud hum...sort of like a ground wire is off of something. I did buy a new power supply with the three prongs...nope.
I check my guitar over with a multimeter to see if there was a ground broken there...nope.
I've plugged in my computer and attached it to the back for a ground...nope.
I have the App connected and use maximum noise gate...nothing changes.
Positive Grid is sending me yet another chord...I doubt that will work. Very disappointing.The hum is SO LOUD I just don't think I've heard anything like it except for a loud feedback, which this isn't. I'm wondering if something in the box isn't grounded right. Has not made any other sound since coming out of the box.

We have heard and learned a lot about humming spark amps in the last time. If you can make a video it could help us to help you.

I did already send a video in and should be receiving a grounded power supply. However, I think that I may have solved the issue. I noticed that no noise was present until after I plugged in my guitar, then the loud hum began. I began to suspect the guitar cord.
So I went to my local music store and bought a new Roland cord for premium dollars.I think that was part of, if not the whole, issue. Certainly I know that a grounded power supply will help with noise but the volume of the hum I had was concerning.
Lesson...buy and use a quality cord!
