I am selling my Positive Grid Spark NEO because I no longer need it. I was using it until recently, so it works perfectly. The serial number sticker has come off because I used double-sided tape to stick it to a wall. Please be aware of this, although it doesn't affect the functionality. BOSS Pocket GT GUITAR EFFECTS PROCESSOR No box. Only the charging cable is included. This is a rechargeable, compact multi-effects processor and amp simulator from BOSS. It has the same sound quality as the GT-1 and allows you to use Bluetooth to play YouTube or music, and you can also edit sounds with an app. It also has an interface function, so you can record yourself playing, create demo tracks, and it's small and rechargeable, so you can easily play through headphones during breaks at band practice.
