« Great amp - with critical problems »

Let's start with the positive :
The sound is good
The possibilities are theoretically very good with the app : pedal emulations + looper + smart jam + ai tone builder etc...When it works, it's great. I love the idea behind this amp.
Now the negative when actually using it :
What I described above is not fully possible because the bluetooth connectivity is probably the worst you can ever have (and I thought reading comments before it was just rare cases before buying it, but it's actually amazingly true), and when this doesn't work well, Spark loses a lot of its theoritical capabilities. 2 main things that sum it all :
-the connection in bluetooth with the app is not stable, it happens quite often that we we loose the connnection with the phone, hence we spend as much time reconnecting it to the phone than actually playing the guitar which ruins the experience. It is also an issue with other positive grid amps (like the spark Go I own too). Of all the bluetooth speakers I have ever connected to my phone, this one is by far the most unstable.
-I bought the positive grid links, the wireless jack system by positive grid (so same company as the spark 2), and whenever I turn them on, I have some bluetooth issue. So basically the links create interference with the spark 2, and then my spark 2 cannot connect properly connect to the app with all the bad consequences. How is that even possible that a company sells 2 products that interfere with each other, when they're supposed to be made for each other !!!! That also mean that Spark 2 shouldn't be trusted for any kind of live performance as the risk of interference is high.
When turning the links on, the issues I have are : immediate unability to use the looper with drums + the phone gets disconnected from the amp, so basically loosing all the connected features which make all the value of this amp.
Don't buy, unless Positive grid makes some major update.
