Ratings and reviews

The app is fantastic when it works. The sound bank is robust and fun to customize sounds. I upgraded to the Experience Hendrix package and the tones are incredible. This is all contingent on the app actually connecting to the Spark 40. I constantly receive errors that Bluetooth has failed to connect, or needs to pair or disconnects minutes after connecting. I turn everything off, restart, ensure Bluetooth is not connected to other devices, clear the app cache, etc. Frustrating to say the least.

Update: the crash reported below is now fixed, but there is a new issue with the app not able to save videos, because of lack of permissions. But storage acces is not available to the user as a config option, so you can't enable it (the app needs to request it) Crashes when downloading assets for Smart Jam, time and again. Otherwise, the spark go wound amazing and the cudtomizarion options are good and fairly realistic. The other issue is the lack of a proper looper function.

It's a great amp and app, but after the most recent update, trying to download resources for Smart Jam crashes the app. Cannot use this feature at all right now. Hopefully Positive Grid sees this and can fix it. Edit - the smart jam resources have been fixed, but now we are having connectivity issues. I have done all the troubleshooting save from factory resetting, and it still won't connect to the app.

What's new

Fixed an issue where the guitar volume would suddenly cut out when Control X is connected to Spark 40, MINI, or GO, alongside other bug fixes and performance improvements.
