Are you a frequent user of your FB9? Have you been moving to higher levels of jubeat gameplay? If so, you may have noticed that the stock I/O board has issues hitting notes on time or that it struggles to handle simultaneous presses. This upgrade board solves all these problems and more. It features perfect, low-latency performance as well as an optional P4IO connection mode for use with arcade mixes. (Keyboard mode is still available.) The board mounts seamlessly in place of the original board and the upgrade process is quite simple: just open up the FB9, unscrew the old board, screw in the new board, and reassemble. This product is a must-have for any jubeat player looking to improve beyond low-level charts.
Note: This is not an official part by DJDAO. This is a replacement board manufactured by ZhouSensor.
