So I bought a used Digitone and noticed a couple of things. The A/C plug seems to be aftermarket and froze on startup however hasn’t happened when i restarted it. The lighting when turned on seems off and I attached a video of this. Also the mute functions I could have sworn I remember some turning blue and or purplish when I hit FUNC T1/T2 etc. I ran a reboot to check for errors and 0 were reported. Should I be concerned with this? Any tips and or help is appreciated.
