Hi Janek, I promise that my question is a long drawn out question this time. I was wondering about a certain that you had during the latest webinar you hosted. I think you called the "tremolo effect" but my best description is that it's sort of that Godfather sounding effect. My question is how did you develop that technique and could you give sort of starting place to develop that technique. I was completely watching with my mouth ajar for the mere 9 seconds that you displayed that. Must know how to do that.
