Looking really good, brother,,,and I LOVE the use of the metronome! I think you said it best yourself when you touched of the following 2 items:
1) When you alluded to the fact that you are more comfortable playing scales (in this case, the A-minor Pentatonic), then stick with that! Remember, Pebber himself always stresses this. He uses a combination and/or a hybrid of techniques depending on what the music calls for (single string runs, scales, chords, tremolo picking, palm muting). I have incorporated this into my playing, and got much better as a result.
2) Practicing can definitely get you the results you seek, as long as you practice right and on a consistent basis. I first got to know Pebber back in Summer 2008, and he introduced me to Scalpel and Sarod Picking Techniques. It took me 6 months of practicing each technique, before I felt comfortable enough to incorporate these techniques into my live playing. Like Pebber, I developed a Scalpel/Sarod Hybrid Technique. However; in no way does this mean I "mastered" either technique. Based on my research, most experts agree that it takes at least 10,000 HOURS of practicing something in order to become advanced.
Even despite this, here I am over 7 years later, and I am still working on improving these techniques introduced to me by Pebber!
Thank you so much for your post, Muso7444, and keep up the great work!!!
