Back at the annual NAMM event in January, we heard of a new guitar that had 18 strings.
Phht. For rookies.
Behold this 20-string monster from 10S guitars of China. The Spring BH Djent 20 Guitar–meaning that like its 18-string predecessor, it requires Djent-style of playing. That involves a lot of muting of strings with the palm of the hand while going nuts with the other.
Oh, and it weighs 50 pounds.
