I love the look and sound of Big Joe Williams‘ guitars. He took a regular 6-string guitar with a raised pick guard, doubled the first, second, and fourth strings (like on a 12-string guitar or a mandolin), and then added a pickup and tone pot. With duct tape and paperclips, it seems. He would apparently play these guitars through amps jerry-rigged with pie tins and beer cans.
Here he playing his most famous song, Baby Please Don’t Go, which has now become a blues standard:
(The original video I had linked here of a live performance has been removed. Here are versions from 1935 and 1941 instead.)

He was true blues. He lived the blues. Start here on your road of blues music and when you’re finished here, go on to Lightin Hopkins.
