Roger - To make a S-12, I must slightly modify the heavy rib configuration on the changer-end endplate...that is, make a second foundry pattern. I wanted to "field-test" a S-10 for a few months before building a S-12. I used a 3/8" diameter changer axle on the prototypes which would be increased to 7/16" diameter for a 12-string guitar...not much of a difference, but way more than enough to do the trick when cross-sectional areas are totaled up. The other physical dimensions of the guitar would remain the same....7.00" wide and 27.50" overall length.
The main problem I have encountered with my prototype to date is that due to its just-over-22-pound weight, and using plastic leg tips, it skids on linoleum floors. I'm going to switch to the rubber leg tips and that should erase that problem for good.
While I'm convinced that many factors enter into the tone equation, I have concluded that the main one on this guitar is the 24.50" scale...not 25.00" or 24.25"...but the magical Fender 400 24.50" scale length. Other factors would, of course, include the wood neck/deck not being attached to the changer, the solid nut as opposed to using rollers, the G-L's 10-1 pickup and stainless strings, the shortness and resultant rigidity of the frame design, and integrally-cast endplate configuration.
I hope soon to be able to break away from my work enough to record a 4-track demo of this little guy. 'ebb' has agreed to post the sound tracks on the Forum for me when they are completed. At least one of those four tracks will include my recently-completed "Guit-Uke"...a 1932-vintage ukulele that my mother bought then and gave to me when I was seven. It was in bad need of restoration, but I didn't want to re-build it as a gut-string uke, so I made it a solid-body mini-guitar complete with adjustable tremolo bridge and Bill Rudolph pickup. It's tuned like a tenor guitar capoed at the 12th fret...DGBE, but one octave up. I wish I had a clone right now!!!

now that i am recently unemployed, as in forced early retirement, i should be able to cobble something together soon. i can report that i have pretty much abandoned my fender since receiving the ontrak which has a direct mapping of sneaky's b6 (with an added "f" lever)to 5 and 5 on a 10 string with 2 original bl 705s

Looking forward to hearing it. Thanks Ebb. Since my wife graduated nursing school and is back at work I'm considering a brand new cutting edge steel machine. Hopefully Paul will be taking orders for the Ontrak. Hopefully early retirement is treating you well.

John - You'll be happy to know that on Monday afternoon, I picked up a box of castings at the foundry. Among those castings are several sets of 12-string endplates. I have decided to put together a S-12 E9/B6 guitar...a prototype with 7 FP's and 6 KL's, plus the Sacred Steel lock. I have been questioned about the possibility of a 12-string guitar on numerous occasions recently. I want to see just how well a pull/release system adapts to that tuning and vice versa. It will admittedly be a tight squeeze, but well worth the try.

Paul's work on my ZB
Paul just finished a major, major master work for me, a total re;-work of my basket case ZB. The traditional ZB system was gutted and in it's place a Kline-like system.
Almost everything underneath was redone including made the pedal rack and legs. The lacquer work was also not ignored. Pickups, tuning keys and fret-boards and the wood were all that remained of the original. Otherwise the rest was all Paul's work. The ZB case was also made more steel guitar safe and wheels built into the case were added.
It was a true labor of love; I hope to post some photos prior to leaving for China in a few days. A thousand thanks once again, Paul.
