After 7months my spark stop working. there was a terrible hum and when I plug the guitar nothing happened... and on Gain the hum was even higher so high that I couldn't keep the amp on.. I got it replaced, it work for 6 days and than again same problem and I had the new grounded power supply... I sent back (and I am waiting the new one replaced) and in the meantime I bought another one and I got it... it worked for 5 hours than the same problem again...
I know it is not electricity problem because if I plug all my others digital amplifier from Yamaha nothing ever happened
does this problem happened to anyone? the customer service doesn't really help explaining to me what can be the issue.
thank you for any help

got the same issue, guitar input is just dead.
I contacted the helpdesk. They send me another replacement, it takes weeks, but it will come.
However, the 1st replacement only last for few days until it got the same issue again.
Then I contact helpdesk again, they send me the 3rd one ... so far it's working.... dont know until when ...

It is the second time that I have the same problem with Spark 40. First time I sent it to the technical service in Poland, they sent me a new one amp and I thought that everything was fixed with the new grounded power unit (The first amp hasn't a grounded power unit). Two weeks later I have the same problem again with the second amp. The problem repeats exactly, a terrible hissy noise with plugged and unplugged guitar. The guitar don't sound amplified and not working anymore. The technical service said this time: "I will keep you posted on the shipping label to return your Spark amp to our local service center FOR REPAIR. The whole repairing process will be done in 10 business days." But my one year warranty expires in two months. What will be the support next time, out of warranty? Pay for repair it without any faith in this amp? I have two Marshalls (35 and 5 years old), two Fender (30 and 10 years old) and one Peavey (20 years old). I has not any problem with them, plugged in the same grounded outlets.

@ma-gomez56 see my other reply on the other post you put your dilemma on. Basically I’d challenge the warranty after the message from the CEO saying the spark had a 2 year warranty and to apologise over problems. Not only that if they’ve already replaced the amp surely the warranty would start again from when you got your replace amp unless stated that it only had a certain warranty like 3 or 6 months with the replacement.
