"Graham Caldersmith's #101 violin has an impressive sound. The sound is warm, clear and projects extremely well. I've been performing on the instrument for 10 years, since winning the Kendall National Violin Competition in 2006. I have been so satisfied with the instrument, that I haven't felt the need to spend lots of money buying an older instrument. Thank you Graham, for making this beautiful violin which I continue to play each day."
