Robben Ford – Blues Solo in Bb

Here's a nice solo in Bb, using the major and minor pentatonic scales and more importantly the Bb minor 6th pentatonic scale (also called the pentatonic added 6th).

Basically, you just replace the 7th by the natural 6th in your minor pentatonic scale.

Also, check out the use of chord tones to underline the changes, for instance over F7 & Eb7 chord.
