I work by appointment only and require a 24 hour notice so I may schedule my day around your guitar. I work from my home and my available hours are Monday - Friday (9AM - 5PM). Also the ocassional Saturday morning if the weekend is the only time you have available.
I understand most have day jobs. So you can drop your instrument off (before or after work) and pick it up that afternoon or the following day. Not 2 weeeks(?).
Never more than 24 hours.
Not to worry, your instrument is safe, secure and kept in a climate controlled envirement.
