The Workshop Violin has been very well received. It is totally made in-house, using the most seasoned and stable materials that can be found. Every violin is hand finished. The varnish scheme may vary somewhat from instrument to instrument (straight vs. shaded). However, shading is never overstated. Greg likes to allow the texture of the Oil Varnish to be displayed, as opposed to the smooth "plasticized" look that is often common with modern student-level violins.
In addition to being very easy to play, the Workshop Violin has a balanced and robust sound most often associated with instruments in a much higher price category.
Workshop violins are in good demand, so it is rare that we have instruments unspoken for. However, we have been busy making so please contact us for information as to availability at (630) 906-0244.
