The review is for the new Spark 2, which was released in September 2024. The sound is on another level. The app is the best there is; with the help of AI, it scans whatever song is playing on your phone and immediately gives you the chords to play along. It has an amazing looper, and together with the AI, it can follow you, creating a band of different instruments that follow what you play. One of the best things it has is the unlimited possibilities for virtual effects, and it's very useful and convenient when you select a song; you can find ready-made preset effects that others in the app community have created and shared. For example, you select Pink Floyd - Time, and you can choose similar guitar effects that Gilmour has on the guitars (similar). It is worth the money both in terms of amplifier power and sound quality. It can also be used as a Bluetooth speaker and has a Line Out and headphone output. There is a battery option for an extra 79 euros. Purchased from a well-known store in Germany. I hope they bring it to our stores soon.
