JBL BandBox Solo AI-Powered Practice Amp

The JBL BandBox Solo AI-Powered Practice Amp is a compact practice amplifier and speaker for guitar, vocals, bass, drums, and everyday jamming. It uses Stem AI to separate vocals, drums, and guitar in real time, while built-in amp models, effects, and practice tools support focused playing.

Built for musicians who want to buy a compact practice amp with Bluetooth streaming and app control, BandBox Solo makes practice more flexible. Players can mute original parts, isolate difficult sections, adjust pitch or key, and shape tone without needing a separate pedalboard or full amp rig.

Its 18W RMS full-range design delivers bold JBL sound from a 2.25" transducer, while USB-C audio interface support lets players record directly into a compatible digital audio workstation. A headphone output supports quiet practice, and the rechargeable battery provides up to 6 hours of portable use.
