I mainly play the blues but I do love the playing style of the great Charlie Christian. He played a lot more with the major third and sixth instead of the minor pentatonic giving him a lighter jazzier sound.
Playing a Gibson es 150 straight into a Gibson valve amp his sound was clean and warm. He was hugely influential on Chuck Berry who also played using a similar scale but of course adding his own unique rock n roll style.
Sadly he died at the young age of 25 in 1942 but he left a huge legacy for us all to enjoy . Check out the clips below.
