Gambale is an excellent guitarist but I can't stand his music either. I got an instructional dvd a couple of years back, I learned a couple of cool things from it but it's just not my style so I put it back in its case and haven't opened it since. The key to learning guitar from dvd's is to get something that you like the sound of. How about Vinnie Moore, Yngwie Malmsteen, John Petrucci or Michael Angelo? THey all have different styles and are a lot more 80's shred than Gamabale who to my ear is more fusion and less 'metal'.
