The Jelly Roll Bakers

The Jelly Roll Bakers is a unique blues duo featuring two outstanding Colorado music veterans – Johnny O. on acoustic guitar and vocals and Andy Irvine on acoustic bass. Their sound and repertoire consist of traditional American blues and authentic ragtime guitar with a powerful bottom end. The magic of this versatile combo is presented through their original compositions and improvisational blues jams.




Home Studio

Much of his time is spent working on his own original music but now he has branched out by working with other talented musicians. Every project is different , Johnny O has been producing , engineering, arranging , and in many cases playing various other instruments on these projects. Check out the Home Studio page and enjoy some of the new tunes.




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.
