I work by appointment only and require a 24 hour notice so I can schedule my day around your guitar. I work from my home shop and my hours are (9AM - 4PM) seven days a week.
I understand most of you have day jobs. So you can drop your instrument off (before or after work) and pick it up that afternoon or the following day.
Never more than a 24 hour "turn around", unless parts need to be ordered.
Not to worry, your instrument is safe, secure and kept in a climate controlled environment.
