The Dean Bass in a Box Bass Headphone Amp lets you plug in your bass, put on the headphones, and start playing. It’s the perfect practice tool. The Bass in a Box fits in your hand (or in your gig bag pocket!), yet allows you to practice as loud as you want, and still stay on good terms with the old lady next door! Kick in the speaker simulator and you’ll find amazing low end, and select between flat, bright and normal to get just the tone you want.
