I've got a new video up that might be helpful to if you wanting to go low and you don't know how low you want to tune. I took a riff and then played it through from B all the way down to D1. So hopefully this gives you a rough idea on how low you'd like to go. I used my PRS Mike Mushok from B to G, and then my Squier Stagemaster 7 with a baritone neck conversion from F# - D1. Let me know which low tuning sounds good to you. Personally I like between G and F. But there's no right or wrong answer. Just thought it would be interesting to give a quick run-through on the different low tunings.
