Repair times are not gauranteed, every guitar is different! Special orders of parts need that are not in stock may cause a delay. Though our repair techs are scheduled to be in every day, they do sometimes get sick, take vacations and celebrate holidays. 90 day warrany offered with every repair, no stipulations, we just wanted to reiterate that point! All action adjustments are set up to be as low as they can be without buzzing at normal pressure and standard tuning. If you would like an action that is a little bit higher, play heavy or would like your guitar setup for a non-standard tuning, you need to let us know.
