Great lesson Rob! I always liked that diminished approach in the Blues and make use of it very often - most poeple think of Malmsteen's neoclassical style when hearing diminished and harmonic minor......Anyways, I think it is utmost important to get a feel for this "strange" sound, which means that in the beginning when you apply it it will sound a little bit like playing scales, but you have to hang in there until it flows naturally :-)
