LAG HyVibe The TNHV15ACE, the world's first nylon intelligent guitar, combines the world's lutherie with the revolutionary HyVibe system. The HyVibe system allows you to amplify your guitar with built-in effects, create loops and even transform it into a Bluetooth speaker. This instrument will inspire you to play more indoors, outdoors or on stage. Whether you're playing with streamed backing tracks, creating your own effects with the LAG mobile app, or using a looper to work on new solo tunes, you won't want to put LAG HyVibe off! The TNHV15ACE has a solid red cedar top and Cognac Brown Khaya back and sides.
