J.J. Cale

JJ explains in this video how he bought this Harmony acoustic for $50 and did some custom work to it by taking the back off and adding electronics and five pickups

"In 2002 I started playing a Danelectro Convertible because it’s light and has acoustic properties. It’s one of the newer ones made in Korea. I like the sound of it; keeping it in tune is a little rough. I had a Martin custom-made in 1991, a 000-45 with my name on it. That’s most of the acoustic guitar you hear, but all the electric leads are the Casio. On “The Problem” I play a gut-string solo on a Ramirez with a piezo. The Convertible is on one cut, “These Blues.” I don’t play guitars without modifying them. I put a piezo in it, and stereo it out. If I’m playing solo, the Danelectro is fine. But if I’m playing with a band, doing hot licks, I use the Casio." http://www.vintageguitar.com/2953/j-j-cale/
