For players of all levels, I give you a series of foundational principles for successfully amplifying your harp and getting that full, rich, ballsy Chicago/West Coast sound made popular by Little Walter, Big Walter, Paul Butterfield, Kim Wilson, and many other classic and contemporary players. I talk about mics, cupping techniques, speaker cone size, even and odd harmonics, solid state vs. tube (valve) circuitry, and the importance of overdriving every stage of the mic/preamp/poweramp/speakercone chain. Using my collection of vintage Fender, Premier, and Kay amps as evidence, I explain the magic of small-magnet speakers and show you the way in which speaker configuration affects the amp's sound and playability. Every amp has an ideal operating range, above which it feeds back but below which it refuses to sing; I show you how to dial this in. Note: this item is a zip file consisting of a long (56 minute) video plus an article I wrote for The American Harmonica Newsletter in 1993 entitled "Getting the Big Sound: Adam's 10-Point Guide."
