I think these old videos of Synyster Gates playing should really give everyone hope. You can hear that his play is a tad sloppy in some moments, but look how good he is now :D Practice is key
Even when Johnny's bass strap fell off, they looked so professional. They continued to play and act like nothing hapenned. One of my favourite bands! <3 R.I.P The REV <3
It sounds fairly well, but instead of using autotune, try just practicing with your own voice, I just find it really unprofessional when people using autotune, especially when it's someone who cannot sing and refuses to practice..
