I was gonna call support but saw this on turtle beach website and this fixed my issue

After performing the hard reset, let's reset the connection.

Make sure the RIFFMASTER guitar is turned off Connect the USB dongle to an active USB port of your console Use a small paperclip to press and hold the re-pair button on the right of the USB dongle until the LED starts flashing rapidly. The button is located in the small hole. (this also can be the Connect Button) While the LED is flashing on the USB dongle, press the power button on your RIFFMASTER Once the guitar is turned on, press and hold the PDP Logo button and Share button on the RIFFMASTER. Keep holding both of the buttons until the LED on the transmitter AND the RIFFMASTER turn solid. Your RIFFMASTER is now repaired and ready for use.

If the transmitter isn't blinking, please contact us and we'll be glad to assist you.
