I posted this challenge on other message boards, but I would dig hearing some of that great Gretsch tone played over this. My goal here was to create a simple backing track that was minor & major key neutral. Any scale minor, major, pentatonic, or whatever in a given key would work with it. This is mostly for learning the fretboard, scales, triads, chord tones and such. Be that as it may, here's my attempt at a backing track in "A" that appears to meet my goal. Feel free to comment, play over it or go get a cheeseburger: Smooth Underground Chill Tips: Download the track to your computer, there is a download link. Place the file in your DAW or just play it through your computer, record your jam session and post it on the internet location of your choice. Enjoy!
