Reference for my fursona's 12 string flying V guitar. Guitar also has a wow bar.

Upper strings get played with a pick he wears on his thumb which allows him to quickly go back and forth between guitar and keyboard. The lower strings being so close to the upper strings has some effect on the overall sound and he can play them separately by picking at them with his fingerclaws.

His signature song is an instrumental work called Ride the Red Rocket
