Excessive hum
-
@garethjknight thank you for suggesting this.. I'll try a different cable... But I've Red other users using wireless system and experiencing the same problem....
-
My hum only happens when using high gain and OD pedal, so I'm not sure if it's the same as your problem. However, it totally goes away when I use wireless transmitter instead of cable.

Update: my issues seem to be resolved. After getting rather frustrated after playing with electric, acoustic and bass, all with noise, hiss and hum so loud that it was practically unplayable, I was getting ready to send it back. Using the volume pot was impossible - the noise was bad enough at full volume but rolling it back a little was excruciating! Unbelievable levels of noise.
So last resort I tried swapping my guitar lead (3rd different lead). Ground loop was suddenly reduced to perfectly acceptable levels and all the other hiss and noise had gone. Even high gain amps were ok with the noise only as you would expect.
So the first 2 leads I tried were causing issues. I have used these with other amps and DI into various recording interfaces with no problems, so I don't think the leads are dodgy, but for some reason the Spark doesn't like them. They are perhaps of lower quality than the one that works though.
Anyone with issues I would recommend trying the best quality cable you have and see if that helps.
Hello, could you please tell us what kind of cable are you now using to solve the humming issue?
If you know the model or brand, it would be very helpful, or even its price range.Thank you

@fasthall What wireless transmitter are you using?
-
Just received my amp in Australia after a very lengthy wait. LOVE the amp but....
Unfortunately I also get excess hum....
Does anyone have the definitive fix to that?
Another issue I find is when streaming backing tracks through it from my iPad the sound of the backing track is quite bassy but that’s tolerable.
If the hum issue is sorted then this is an amp worth waiting for. -
You need a grounded power supply with the Schuko-Plug, not
the Euro-Plug. It must be the big round one not the flat.
On the other end it must be outside 5,5mm and inside it must have 2,5mm.
And have attention, that there is no pin in the middle.
You need a supply with 19volt and 2,5ampere or a bit more.
My fujitsu supply has 4,7ampere an works perfekt.
With a little rest of buzz we must life untill PG revise their useless noise gate. -
Do you get excess hum on clean tones, or is it just when gain is used?

If the hum issue is sorted then this is an amp worth waiting for.Excessive hum in Australia? that is a concern... we got good grounding here, power supply must really be cheap rubbish...
I'll probably get mine this week... I hope I don't get any hum, as it's a newer house etc...
otherwise there's going to a very p!ssed off bogan... mate -
Well time to cheer for the amp is here..Jan 3rd order date #123640.arrived today two days before my birthday ,,dont know if they knew about the hum issues everyone seems to be having before they were shipped but there seems to be ways around it if you want to buy another power supply ..im not going to play it until i purchase one cause i dont need any more frustration since its taken this long to come ..but on initial sussing out its gonna be a blast .connected super easy sounds big for its size so ill be back in touch with final conclusion. also in OZ .players special.

Sorry, I don't know. I've probably had it for 10 years or more. No idea what make it is. It has "professional low noise instrument cable" written on it, that's all

Muslady wireless transmitter ..ebay around 40 dollars .works for me.
-
@mryder Same here mate. Australia too...
-
@pontesilli70 Yes. I am using Xvive and its not 100%. Still getting hum .. Clean tone too.
-
Yep.... Received mine yesterday...Same thing.. Cheap Power supply with no earth. total crap.
Had an old laptop power supply 19V 3.4 A and now its fine.
You would think after all this time they would fix this problem they have known about from the begining. -
If customers buy a reasonable power supply themselves, it is cheaper for PG than to replace all of them at their own expense.

so what are you saying? PG will refund us all $20?
these power supplies cost PG $1.95...
So will never happen -
I say if users can live with the hum or have an old usable power supply lying around or buy a new grounded power supply at their expense, the PG doesn't cost a cent. This is the convenient way ....... for both.
If you want to complain about this bad power supply, you have to write to the manufacturer and record a video that shows the problem and wait again. Then you may get a viable replacement. But I have already read that the same power supply would have been shipped as a replacement.
Most will probably choose the easy way.
Therefore PG continues to ship its amps with these cheap power supplies.
