Watch the Eb Tuning online guitar lesson by Gary Hoey from Blues Rock Reactor
In the following tracks, we'll be tuned down to Eb. Now you may be saying, why would we do that?. Let's talk about it:
When Stevie Ray Vaughan came along, I noticed that his songs were always a half-step off, either in Eb or Ab. And it's not just him - all of the Guns N' Roses' stuff is tuned down too! This got me to start experimenting with the tuning, and I started to fall in love with it. It does make the strings a little bit looser, which allows you to use heavier gauge strings if you'd like.
I recently got to meet Tony Iommi, and he was telling me that a finger injury when he was young made it hard to play the guitar. He ended up tuning down three half-steps to accommodate this, and ended up creating the Black Sabbath sound!
