one of the problem is the communication between alembic and I, lot of times, no answers ore answers late. I dont know how, when they work. The other problem is a language problem, I use lot of time google translation or friends translation.  
I wrote on my FTC the machine heads position problem on the 17 th of may, at this day no answer.  
I dont know their date of vacation, here we dont know nothing about their work.
I dont know how time Mica spend on web/mail for the club.  
The only thing I'm sure for her: the family in first.

thanks for the responses, but I am checking out of this thread

I would advise anyone reading this thread that Alembic has always made it clear that this forum exists as a courtesy.  If you really need to have an answer, then call the factory.  Speaking directly to a human is the best way to get a response.  They've made it abundantly clear that they are busy working on instruments first, and that the forum is a bonus.  If you have a problem, I'm sure they will work with you, but you need to take it upon yourself to make contact directly.  The fact that they don't edit content with the exception of inflammatory and unrelated speech, and furthermore, the fact that threads like this even exist, is a testament to their honesty.  It is also true that this is a small family business.  If one person is sick, then production is slowed.  We're not talking about the Fender or Gibson factories.  I'm sure that some people prioritize their work before their family, but Alembic doesn't.  Who here doesn't love Alembic because of the fact that individuals and not a corporation build these instruments?

If we discover a defect while working on a build, we scrap and start anew. As others have already stated, there's years of Factory to Customer threads to show when that happens, we do as I've described. The downside of that is it will add to the delivery date.
 
I will point out that we do not claim perfection - it is something we strive for, realizing that it's not attainable and it's differently defined by different people.

Thanks for the response, Mica.
