He helped form and played guitar with the East Side Pharaohs for around eighteen years. Becoming interested in guitar effects and electronic music synthesizers, in 1981 he took a job as an Audio Specialist at the School of Music, University of Iowa and started building an analog synth. He later finished a MA. in mathematics, and then taught both mathematics and computing at colleges and universities in Minnesota, USA. Together with Jerry Hagen he founded Midwest Analog Products, which he closed in 2005 to teach full-time. He retired in 2013.[1][2][3]
