Query: Another Master Teacher

Frank Gambale is not only an excellent teacher but is also a touring and playing musician. His style of teaching is precise, balanced, and very thorough. When I first started using this of course it was slow going, but just as he taught, it became natural and effortless once I caught on. It is full of gems of new ideas and arenas I had never known existed in the world of guitar playing. It stretched my knowledge and playing ability to a new level I had not even considered before. It doesn't matter what style guitar you play this will be an additon into your minds encyclopedia of guitar knowledge.
