Guitar Lessons with Johnny O.

Founder of the Johnny O. Band, John Ohnmacht has been playing on stage for over 30 years. In that time he has perfected his technique in a wide range of electric and acoustic guitar styles including lead improvisation, slide and finger picking. John has enjoyed teaching guitar for 25 years and has developed a style that has helped countless students reach their musical goals.


By focusing on rhythm, solid scale positions, and ear training , John’s students learn the fundamentals of playing and improvising without being bogged down by the common problem of over thinking music. John has found over the years that this approach proves more enjoyable for the student. Students can expect to learn how the modes really work in improvisation as well as pentatonic, blues scales, and arpeggios. John’s aim is to help individuals break barriers, grow as players and have fun learning to play guitar.

John Ohnmacht teaches lessons out of his home in Louisville, Colorado.
