I played lute for a few years and then switched back to guitar but I brought back from lute to my guitar repertoire plenty of beautiful early music pieces. They do not need to be transcribed to guitar, I just change the guitar tuning to lute and play from original lute tabs (well, low basses do need to be transcribed to octave higher).
