Hey Marty! You have been the ultimate influence on me ever since I heard RIP and Cacophany! Your chemistry w/ Megadeth really inspires me to further my musical career. I even have your signature guitar. It really sounds and feels great, especially during solos! Although I have always been a little confused about the one knob on it. It seems to be a tone knob, but it also affects the volume a little! How do you set the knob during rhythm and solos??
