It is an unwritten rule of our trade that recording engineers approach the electric guitar amp with a Shure SM57. Typically, it is placed up close, against the grille cloth, a bit off-center of the driver, angled a little. These recording decisions serve us well, but what do they really do?
This presentation analyzes the key sonic contributions of the guitar, the amp, the microphone, the room and the microphone placement. The spectral effects of these recording variables are quantified and discussed. For any given guitar, and any given amp, the tone is still radically shaped by the microphone frequency response, off-axis coloration, proximity effect, comb filtering, driver break-up, and more. Case narrows the vague and complex guitar amp recording ritual into focused strategies so that we may all develop a more effective, more productive approach to tracking one of the most important instruments in the history of music.
Alex Case is the Graduate Coordinator for Sound Recording Technology at the University of Massachusetts Lowell, teaching undergraduate and graduate courses in audio and acoustics. His research focuses heavily on the technical foundations, creative motivations, and aesthetic merit of recording and signal processing techniques used in multitrack production, leading to the publication of more than 100 articles and the book, Sound FX • Unlocking the Creative Potential of Recording Studio Effects, from Focal Press.
In addition to his local AES activities, Case has led half a dozen Tutorials at AES Conventions (New York, San Francisco and Europe), and presented more than a dozen papers at Conferences of the Acoustical Society of America. He has been an invited speaker internationally at locations including the Banff Centre for the Arts in Canada, Fermatta Academy of Music in Mexico City, the SAE Institute in Milan, and the Shanghai Conservatory of Music. Case is a Fellow of the Acoustical Society of America and holds a M.S. in Architectural Acoustics from Rensselaer Polytechnic Institute, a B.M. in Music Production and Engineering from the Berklee College of Music, and a B.S. in Mechanical Engineering from Rice University. Lastly, it should be admitted, he is a really mediocre guitarist.
