I needed a small amp that I can easily carry on my bicycle for jazz combo gigs in small venues. Getting a great jazz sound is quite important to me, and since the other small amps I tried were "just OK" I decided to take a chance on the Spark 2 before its official release.
The setup and learning curve were quick, and I was able to dial in a very convincing Deluxe Reverb tone easily. The next night I took it to rehearsal with 16 piece Latin jazz orchestra with drums and percussion. This group is LOUD, and the Spark 2 held its own - I was even asked to turn it down! Since then I've had lots of compliments from other musicians. The FRFR sounds great when streaming music with Bluetooth, so now I find I'm using the Spark 2 for practice more than my main amp.
I've only just scratched the surface of features and tones, and I'm really happy with it. My only criticism is a small one: there is no spring reverb, and the alternatives are good but not great.
