You can craft your signature sound with more than 60 traditional and boutique effects, such as octaver, bass synth, and fuzz. Recreate your on-stage sound with 9 classic amps and cabinets like Fender, Ampeg, Aguilar and more.

You can play your bass to 68 different drum patterns. The B1X Four series offers a built-in drum machine with a variety of rhythm patterns in 4/4, 3/4, and more. Lay down a bassline up to 30 seconds, and then endlessly overdub your performance to build a dynamic, multi-part arrangement.
