Good but problems - updated

After waiting several months I received my spark amp today. The various amp models work fine and sound better than I expected. The smart jam feature also works quite well. However, I am having a serious issue with the auto chord feature. I synched the app with my Apple Music account and downloaded several songs, however when I tried to play along, none of the songs would play. For most of the songs the app created a chord chart that was fairly accurate ( I downloaded several songs I know well to see how it wold do) but none of the songs would play so that I could play along. Since auto chord was a primary reason I purchased the amp, I am not pleased. I updated the firmware, turned the amp on an off and deleted and reinstalled the app on my iPad and my iPhone. I also made sure the amp was not connected to both the phone and iPad at the same time. Nothing worked. I have emailed positive grid and I hope there is a solution, but I didn’t find anything in my online searches. - UPDATE - positive grid responded to my email within a day informing me they had updated the app to correct the problem. The auto chord feature now works great. Loving the amp

I read the criticism regarding delays in orders. With great trepidation...I finally pulled the trigger and just settled in for a long wait. I placed the order on Sunday and received the amp on Thursday. Four days. I was shocked but pleasantly surprised. I figured the myriad reviews singing it’s praises were pure paid rubbish. I was skeptical, to say the least. After Plugging in and fiddling around with the straight amp, then trying out the presets...I was grinning ear to ear. Then I downloaded the app and an hour and a half disappeared in mere seconds. I had to force myself to stop and turn it off for the night. I was like a kid in the candy store running from one flavor to the next. It is simply outstanding. I don’t expect it to be my one and only amp. For its purpose of practicing, chasing tone, jamming to backing tracks and potentially using it to record to the computer...absolutely brilliant. I am completely and utterly in love with this feisty amp. The flexibility and control are fabulous. I don’t understand shipping the cover separately. Still no word on that item but at least it’s not the other way around.

Completely Great!!

I ordered my amp in February due to the pandemic I did not receive it till a week ago in July, so I was wondering if it was worth the wait, and I would like to say this amp is completely great portable the electronics are sounding crisp the way the app works is wonderful, and if it only had the features of the jam with you that would be more than enough everything else is just the icing on the cake but to turn it on pick a groove or create one and jam along with it with state of the art effects is completely great I am so happy thank you so much. And so reasonable in cost. Highly recommend it’s a game changer in portable practice amp but also super loud for a small thing it also came with free digital recording software studio one 4 by presonus . I am playing it right now!!! Order as fast as you can I am not kidding!!! Luv luv
