We had a housewarming party this weekend and...

I can feel your pain!
My first guitar has a huge dent because of a friend. That's why I won't touch anyone any of my instruments, except other musicians that know their (personal) value.

Cheers, but not a single one of those luthiers is anywhere near me, and I'm not looking for a local music store, as I'm more than familiar with their... "repair" services. Soundwell had some knowledgeable folk, but that shop has been out of business for ages.

The only instrument luthier I know from here quit in 2007.

Holy fuck, I'd go berzerker on the cunt who did this.
That's the reason I don't let people bring guys I don't know to parties of mine. Never works out good.
