So, I ordered a rosewood body and neck from a US based builder via. Reverb. He has hundreds of 5* reviews, seemed to do quality work and I was happy to trust him. I pay around £650 for the body and neck, which arrive with dings and he refunds me $60 and I'm satisfied. I then took the guitar and all parts accrued to a company here in Paris to have the guitar assembled, I get it back, great work and I love the guitar. Fast forward to 2 weeks ago, I go away for ten days and return home to this ugly looking crack down the join of the body. This crack wasn't present when I left and nobody has been in my apartment.
See images below. There's an image of a piece of paper with pen marking how deep I can fit the paper into the crack. I have no idea how far the crack extends because of the pickguard etc.
A few people on a few guitar communities have remarked that it probably needs separating and entirely regluing and although just unsightly at the minute, could turn into a structural issue and affect the guitars playability.
I opened up dialogue with the builder via. Reverb and after some back and forth, in which he claims there's "no way" the body is separating and that it just needs filling, he suggested I tear the guitar to pieces, ship it back to Miami, Florida (I'm in Europe), have him fix it and post it back to me; something I really didn't want to have to do. However much I appreciated his offer, I countered by suggesting I have this fixed in situ at his cost, he refunded me a meagre $60 (without prior agreement). I sent him a message asking what happens if the repair costs more than that (which, living in a major European capital, it ABSOLUTELY will) and he replies simply saying "Sorry buddy, that's all I can do". SURELY he's responsible for the integrity of his work here and i'm entitled to more than a courtesy $60? I'd understand if it was a crack elsewhere that could viably have come from me damaging the guitar but straight down the join? I've only had the guitar assembled for a few months.
I'm a total loss here and don't really know where to go. Any advice on the crack itself and also the Reverb proceedings I should undertake would be hugely appreciated. Such a bummer when something you've spent so much money on cracks.. in half.
