Spark Guitar Amplifier, Electric, Bass and Acoustic Guitar 40-Watt Combo Amp, Mobile App

The Spark arrived on time ,well packaged (Minimal Plastic)Although I haven't had time to upload the app for more functionality , their are plenty of good sounds right out of the box. Shimmering clean tones to various dirty sounds depending on use of gain. All in All tremendous value for money and looks great in any setting

Stopped working after 1.5 years of moderate use. The audio cuts out for both guitar and bluetooth after 10 minutes of use, then the audio comes back after another 10 minutes and the cycle repeats. Can't use it anymore. after checking the forums others users have also experienced the same problem. Looks like a manufacturing defect. Contacted Positive Grid and they said the best they can do is to send me a new unit at full price minus shipping. I was hoping that it would last for a few more years. Now it's sitting as a decoration piece on my bookshelf.

Sounds very good (this was when purchased)18 months on now from purchase and spending hours trying to figure out why the speaker cuts out after a few minutes of use.Lots and lots of comment on this all over the internet. It seems the most likely culprit is one component goes out of certain parameters and cuts out the speaker volume.I will send email to the manufacturer but judging by other peoples comments it does not look very positive.Yep it looks like all I get is a bot replying to my emails to their customer support - product provider has run for cover - what a pile of junk.Not impressed given only 18 months of use.

Switches off after 5 minutes of use.Positive Grid will not help you.If you receive a faulty unit like mine, good luck. Be ready for useless emails asking you to send it back to US.UAE is not serviced by them and they do not have return facility here.

If you see to experiment quality and features, this quality is indisputable. DO NOT WASTE YOUR TIME WITH negative reviews, its worth every penny.That best.
