Very disappointed with Spark



  • I got a Spark, really looked forward to it arriving. I had seen all the videos etc. This was ideal for me around the house. It arrived very quickly here in the UK. All was great until I switched it on. The amp is crazy noisy. really bad earth hum. I contacted customer service, who said they understood and would send a new power supply to me, a three contact grounded supply. I was promised a grounded supply on the 10th November it is now the 25th and no supply. This is not good enough. It's virtually useless without the proper power supply - Hum City. Very disappointing.



  • Welcome to the Humming Club...

    I'm waiting for my grounded PSU since 4th October ...

    First, they told me I would have it 'at end of October' ... (guess what.... 🙄)

    Then, last week I re-contacted the support asking for more info , they said 'the PSU were blocked at US Customs, your PSU should arrive within 5-10 days' ...

    Since I live in France 😶 , I replied that I found really strange that my PSU is 'delayed' because of US Customs 'block' , since it should be shipped directly from Asia ... 🤔

    They replied : "same delay as U.S." (Read: "same bullsh*t" )*

    Honestly , I'm really disappointed by their customer service ... and don't understand why they continue to ship ungrounded PSU knowing that so many people complain about it ...

    WAKE UP POSITIVE GRID !!! 🤬



  • @benoit_mich

    hi They sent me a mail saying that most people don't have the hum issue. Seems that is not true! They gave me the same pathetic customs excuse too. I have asked for the spec of the PSU . I will find one on Amazon and get it next day. PG Cs is very poor



  • @dwhfish The specs are 19V, 2.4amps (or higher -- just don't get a power supply that outputs a lower amperage), connector is 5.5mmx2.1mm (although 5.5mmx2.5 works well also), tip positive. They can be purchased in the U.S. for around $20-$30. I have no idea if that price translates to other countries.



  • Yea same here .really bad hum noise. Hope it sorts it when it finally gets here been over 2 month now



  • Same issue here - have reached out to support asking for new PSU and so far no response.



  • Follow up to my previous post:

    I finally got my replacement PSU , nearly 2 months after having sent PG support a video of the humming issue... 🙄

    It solved the Humming once for all , so I can say that 'finally it works as intended' 😎

    Meanwhile, I did go Wireless between my guitar and the Spark, which eliminate the hum as well !



  • While you're waiting on the new supply just ground your amp. That will solve the problem.

    Either use a USB cable to hook it up to a laptop or desktop that's plugged in or hook a wire up to a screw on the Spark's case and connect that to something grounded. A water pipe, any metal going deep into the ground or even the center screw on your wall plate.



  • I took delivery of my Amp yesterday, but didn't have much time to do much with it. However, I soon realised that I was another victim of the "Hum". This evening when I got home from work, I decided to try the USB lead idea mentioned, only to find that the hum had gone - Not entirely sure why - but all that was different was the multi-gang socket it was plugged into...either the extension lead or the socket, Bottom line, sometimes it's not the amp,
