To be clear, this is technically a Rock Band 4 controller, but Epic Games added support for a variety of guitar controllers last April, including Rock Band 4 guitars.
By default, the Riffmaster is configured for right-handed players, but left-handed players can use it by removing a single screw and reversing the neck. The Riffmaster has five upper and lower frets as well as a D-pad on the pick guard and an analog stick on the back of the headstock.
The controller offers a 30-foot wireless range via the included USB dongle and can run for up to 36 hours on a full charge. It has a built-in 3.5mm audio jack and comes with a shoulder strap.
As an officially licensed controller, the Riffmaster also has the PS button to open up the PS5’s control center or return to the home screen.
Unlike many PlayStation controllers, the Riffmaster wasn’t designed with PlayStation console compatibility in mind. That said, some users have been able to get the PlayStation Riffmaster working on PC with unofficial third-party drivers.
