By the way, Cuthbert, how do you like the guitar so far?
capnjuan said:Hi cuthbert; I guess I don't understand; that's the neck block in the pic below and nothing in the text you posted above describes it, does it?
cjd-player said:That patent application was filed in 2002. Isn't that too early for Tacoma?
It looks to me like its just a Fender patent on truss rods (neck support rods); not the Tacoma neck block. All 53 claims refer to the neck: the support rods in the neck, the grooves in which the rods are placed, etc. There is no claim in the patent concerning attachment to the body. The description says (paraphrased): that the purpose of the invention is to have a straight neck. It has nothing to do with the body block, or neck to body attachment.
The fact that you have the patent number inside the guitar simply means that your guitar may have those support rods in the neck.
It is possible that the use of the patented support rod neck is a prerequsite for use of the neck block; but the referenced patent has nothing to do with the attachment to the body. The bock must be covered in a different patent application.
Thanks Carl; I thought there was a patent (or one pending) for what's in the pic. Based on the adverlit, I understood that to be the 'patented neck block' device to which the literature was referring. Apparently, there's another patent (or one pending) for the support rod. Interesting that they call it a 'support rod' and not a 'truss rod' and that its patent (or patent-applied-for) is under two individual's names and not FMIC's. Assuming there is or ever was a patent, pending or otherwise, for the chunky black thing in the pic, I wonder if it's under an individual's name too. I spent some time chasing down variations of 'neck / block / Guild / FMIC / graphite / support / patent' .... bupkis.cjd-player said:...

capnjuan said:Hi cuthbert; thanks for the pic. Since the # can't be read, I guess it's the same number on the patent. The FMIC literature refers to a 'neck block' system ... which is readily visible in the pic I posted ... while the patent covers a 'support rod' which formerly would have been called a truss rod. I didn't see anything in the patent that suggested that the support rod was adjustable, did you? Further, the on-line patent doesn't contain drawings of the object inside the guitar to which the support bar connects. The drawable inferences are that the object in the picture is not covered by the patent (no drawings), covered under another patent (but none found), or, for whatever reasons, didn't require a patent in the first place.
This thread began with Scratch reporting problems with the neck on his guitar and, later, Jeff reported problems on his guitar that a qualified luthier couldn't correct. It remains to be seen whether Scratch's luthier can fix his neck or not. My interest in this subject is limited to understanding how the rod/block assembly connect. I had hoped that seeing a drawing of the block would shed some light on the subject. At the end of the day, if the neck can't be separated from the body or without some other means of adjusting the neck angle, I think the ability to re-set the neck to the correct angle is compromised.

capnjuan said:Hi cuthbert; I really hope that your guitars are trouble-free and that other CO/CV owners can get their guitars straightened out. I also hope that FMIC makes a stand-up effort to help with current and future problems in these models. Good luck with your new guitar! John
When I took over Guild, they had started discussions about an instrument that had a bolt-on neck and some contemporary features,” says Wade. “And one of the biggest challenges I wanted to overcome is top distortion.” In his home shop where he builds classical guitars, Wade had experimented with ways to strengthen a guitar’s upper bout with carbon fiber, a concept that would come to significantly refined fruition in Guild’s Contemporary series. On these instruments, carbon-fiber rods in the neck interconnect with a carbon-fiber neckblock. The guitars also feature a carbon-fiber “spider” that fans out into the upper-bout area of the top, creating an interlocking assembly between the top, neckblock, and neck. “How they all connect really does make a difference in how energy is transferred to the soundboard,” says Wade, who refers to the Contemporary-series tone as more “modern” and “immediate” than Guild’s Traditional series or vintage guitars. The Contemporary series is currently composed of two body sizes (based on Guild’s F-30 and F-40 bodies) available as either a cutaway or a non-cutaway (see our review of the CV-1C in Acoustic Guitar October 2007). Like most US-made Guild models, the Contemporary series is available with D-TAR “Load ’N Lock” electronics.
Hi CB and thanks for making the effort. I don't know how many warranted 'neck-block' guitars were sold, how many 'Used'/ex-warranty were sold, or how many FMIC has repaired/replaced under warranty but the 'patented neck-block system' could be, or already is, a costly warranty and public relations nightmare for FMIC. FMIC has started making Guilds at its New Hartford CT facility but according to the information on the F30 for example Here ... click on Specifications, it says the F30 has a dove-tail joint ... no mention of the 'patented neck-block system'; same for the D50 and the cutaway F47RC. If the system were so bullet-proof .... I think you get my point.cuthbert said:... anyway I wrote to Fender to ask them if they can disclosure informations about the joint and if 6888055 covers the block as well, I don't expect a clear answer but if I get valuable information I'll share.
Jeff said:Ureka !!! The neck is off my CO1. Thanks to Cuthbert & Bazooka.
I showed Brady the Pics they posted & the discussion. We gave it another shot this afternoon. She came off clean, the problem seems to have been a bit of excess laquer on the inside of the neck that hadn't cured before the neck was bolted on.

That would be way kewl! 8)
Scratch said:Update: I had hoped Ross the Magic Luthier would have the CV-1 ready by the end of this week. I talked with Ross yesterday, and it is now projected for mid/late next week. Why? He stated he had never seen anything quite like the neck joint of the CV-1. In so many words, he was not complimentary of Guild's attempt to engineer a bolt on neck. Ross has more than 35 years of luthier experience and is highly sought/regarded by Austin/Central Texas musicians. He raves about Guild dove tail joints and considers them among the best in the business. He said, for example, the neck on my Tacoma D40 is among the best he has seen from any production manfacturer. The contemporary series bolt on necks are a great idea without substantive engineering...
Bottom Line: The repair will more than likely run higher than the original estimate of 340.00. Ross is the best there is around these parts and I trust him completely. He has significantly more work to do to make 'The Duke' rock solid. I told him to just do it and I'll request stimulus money... :wink: He also said he's leaning strongly to making it to Arlington in October to meet the 'Guild Guys'...
For what it is worth, at this point, I suggest that you do not take advantage of the eBay CV-1, CV-2 or CD series used guitars that are easily available at bargain prices. These necks are very poorly engineered, not worthy of patent, and will require significant $$ to make them right. I estimate my $899.00 contemporary series bargain will now wind up around 1500.00 before it is up to professional standards. Update next week...
