M SD's logo comes from an ancient Native American petroglyph pecked in stone, high in the Sierra Nevada mountain range. Long ago, small, selfsufficient groups of people moved about the mountains, hunting and gathering, and celebrating rituals. Leaving behind little about themselves, except for these rock figures and a few stone tools. The mark we found, created a thousand years ago, could have been a sun sign, a map, or a symbol of focus and concentration-or yet some mystery we cannot imagine today.
Preface J ust as a great performer spends years learning his or her instruments, so a master designer spends years understanding the complexities of audio circuitry and the science of electronics. For more than 30 years, Richard N. Marsh, author, lecturer, engineer, and inventor, has shared the art of perfecting audio circuits with other designers. Now, his goal is to bring you his accumulated experience in the service of music.
