I started out in the harmonica business building custom harps. Soon afterward, the harmonica companies improved the quality and construction of their harmonicas. Although there are many talented players who require some specialized adjustments, these players did not reach mastery through custom harps, but rather through study and practice. Seydel harmonicas are built to the most precise specifications. Most advanced techniques are attainable on stock Seydel harps. However, I do provide specialized services to advanced players who require very specific modifications. These services include tuning and temperament adjustments, over blow and over draw set-ups, and half-valving.
