JBL BandBox Trio - AI Practice Amp & Bluetooth Speaker

The JBL BandBox Trio AI practice amp and portable Bluetooth speaker is designed to transform the way guitarists practice, rehearse, and create music. Real-time AI instrument separation is enabled, allowing tracks to be streamed while vocals, guitars, drums, or other elements are isolated or muted instantly. Challenging solos can be studied more efficiently, keys can be adjusted to match vocal ranges, and backing tracks can be customized for focused practice sessions. A flexible learning environment is therefore provided for beginners and experienced players alike.

A built-in four-channel mixer is included to support guitars, microphones, auxiliary inputs, and additional audio sources within a single compact system. Classic guitar amp models ranging from clean tones to high-gain textures are supported, alongside essential pedal-style effects for expressive sound shaping. USB connectivity allows ideas to be recorded directly, while portable use is supported through a swappable battery design for uninterrupted sessions at home, in studios, or on the move.
