I like how many people think that near-perfect communication is the standard for companies of this type or size. Mission Engineering has this kind of story. Fractal Audio has this kind of story. LiquidFoot. I am sure a lot more could be named from boutique pedal, amp, & cabinet companies. I think people doing business with these kind of companies generally have the bar too high. When you look at the history it really is par for the course and you have to know that going into a deal.
I am not saying it isn't frustrating, it is, but you have to know going in you are probably going to have to "work it" to get the updates you need. And I think if you are polite about it things in a majority of cases work out.
