Solo acoustic fingerstyle and slide guitarist here.
I used to play electric guitar in bands, but I've become quietly anti-social, so solo acoustic is a better fit at this stage of my life. :)
I've played live plenty in a band situation. Solo acoustic - only a few times, private parties and such. Hope to do more of it in the future.
