Great for practice.

Went back to buy two extra spark neo headsets for my mates as soon as I started playing with mine.

App Getting Worse

Not sure why I bought this spark 40 modeling amp that requires this app to use it but the app is constantly having problems. Can I have a refund for this garbage product?

Connection issues always occur and tones are lost

After a while the app struggles to connect to the speaker and you need to delete the app and factory reset the speaker for them to connect. In the process you lose all the tones you’ve created. Stupid. Go for a Blackstar.

No words-

I cannot even put the app into words it’s just the goat.
