This is a very good point.  Let me give you the 411.

There are workings one-offs of every module I announced this morning. 
Some have been up and running since last early last fall - the Model 
30 amoung them, although in that it exsists in software we are making changes and adding fetaures all the time.  

As far as the hardware however, the circuits announced this morning are all complete and final. I am now in the middle of the PCB art for the Elfs which is the first wave of the newbies. In short, everything I announced today is a go, working and outside of pcb art, complete.  One issue that was slowing these down was the nuts to the new jacks, as many of these new ones cannot be built with Cliffs. Their faceplate topography is such that they are way too dense for the vertically mounted Cliffs.

The 15A however still has one feature that I am not happy with - the 
1 up/ 1 down octave switch.  The circuit i had was not stable 
enough.  You'd set the up/down margins and in a few weeks they were 
both off.  SO in this respect, the 15A is not at the same stage of 
development as the others.

The good news, I think I've come to a solution by utilizing voltage 
references instead of trim pots to set these linmits.  I've not yet 
tested it.  My plan was if I was able to get to that by the time the 
rest of the Elfs are ready to be released that I'd throw it in with 
those and announce it at that time. 

Keep in mind that along with these 15 modules are three cases 
currently under development. It's an exciting and challenging time.  
Exciting because system-level Plan B's are clearly in sight. 
Challenging because there is much to do, and just so many hours in 
the day to do it...
