  My Guarantee
 I guarantee all of my work. My ultimate goal is for you to be completely satisfied with your experience here, and I will always work with you on making sure that happens. I encourage you to inspect and test your instrument here before you leave. After you get home and put some playing time on your instrument, if you feel anything is off, I want to be the first to know. NEVER hesitate to call, as I would be happy to make any adjustments to suit your needs.
I appreciate all of your support and look forward to working with you all in the future.
