I can't re-read the whole thread- Do you have a ZON you're waiting for?
At any rate, I get that an awesome builder like Joe Zon is probably busy in his workshop, doing what a good builder does, and doesn't necessarily have the time, skills, & desire to stay on the PC, answering E-Mails, and/or picking up the phone.
But-If I was long-overdue on receiving a $$$$ bass for which I've paid for most or all- I would not be happy to have him be incommunicado.
I had literally one of the best builders in the World- Michael Stevens- build me a Slant 4 (too good for words).
I was told originally (1) year, it took closer to 2- But- I was kept entirely in the loop on what was happening.
This is the issue I see with those who have not yet got their instruments.
