when playing slide guitar, are there scales that you uses for that way of playing? would you just play regular scales by figuring out where the notes on the three detuned strings are(open g)? right now i only use slide for blues and kind of do basic solos within the chords but id like to be able to solo to anything on slide guitar seeing as im joining a band that plays some country type stuff and i want to use the slide in some songs.
Yes, there are different scale shapes. I usually play in standard tuning though, because I have to switch between normal and slide live.
