Top crack set off by a phone.
And maybe a little low humidity (?) This custom OM is owned and built by Boston singer / songwriter / guitarist Chris LaVancher at Alan Caruth's shop in 2004. While at a recent gig, a cell phone was accidentally dropped by someone on stage. The guitar was on a stand when the phone impacted the top, setting off a 6" crack.
The crack was slightly open so I humidified the guitar for 24 hours and it closed enough to glue up. Hot hide glue, two pieces of plexiglass (one inside, one outside) and a few clamps make up the first part of this repair. Next up will be gluing in reinforcement cleats to help keep the crack from reopening.
