Amazing Grace (Slide Solo) Song Sample    Lesson Sample    (Downloadable) Duane Allman was the master of slide guitar and this solo clearly shows off his expertise. This is played and taught on a standard guitar with the strings raised up to typical slide-playing-height. The guitar is in open E tuning. The lesson starts with a full demonstration of the solo and then teaches the song (all five verses) phrase by phrase, completely "by ear."
