Flange/phase sound

I’ve been trying to record my semi acoustic guitar into cubase and when I play the audio back it sounds like its phasing or flangeing, like there’s 2 tracks playing the same audio (there isnt) please can any one help, im using the scarlet 2i2, ive tried various buffer sizes, disabled control room, and played about with the Asio guard and the steinberg power scheme :cry:
