Roland is proud to announce the FR 8x (piano-type) and FR-8xb (button-type) V-Accordions, the new flagship models in the company’s acclaimed digital accordion lineup.

This factory is part of the Roland Corporation group, whose headquarters are located in Japan.
Both models are filled with all-new features and enhancements developed through requests from professional accordionists, including Dynamic Bellows Behavior technology, on-board battery charging, new sounds and effects, a built-in looper, and many others. In addition to a full selection of traditional accordion sounds from around the world, the FR8x and FR8xb are equipped with over 180 orchestra and percussion sounds, plus world-class Virtual Tone Wheel organs.
