I've sent Jack messages many of time at Midnight, only to hear from him via Twitter a couple of hours later around 5am est. Late night or early start for Jack? Either way, it's impressive! I will add, however, I understand rocknrolldoctor's frustration. Where a response doesn't land the manufacturer and customer on the same page.
I hope our fellow member is able to hang in there a bit longer so the best solution is reached.
