Fucking love my 8 string baritone. There are a lot of videos on YT. The best part is that while the extra strings take a little bit of getting used to, you can mostly just pick it up and play it like it was in standard tuning. I have a lot of fun playing around with familiar tunes, pitched lower.
Obviously haven’t been super active on here, but yeah… mine is a Taylor GT8. Such a cool guitar.
