What's a "reasonable neck? I guess at this point we need more data from Mr. Data himself....... are you talking about steel string guitars, classical guitars, maple necks, cedro necks, mahogany necks? What thickness of the necks? 19 mm at the nut, 22mm at the nut, 24mm what? Do you enter into your experience, the effects of humidity changes?Trevor Gore wrote....."A stable neck can be manufactured from a wide range of woods. Further, if reasonable wood is chosen, the author’s experience has been that it is unnecessary to complicate the manufacture of the neck by using multiple laminates of either wood or composites to add stiffness and stability to the neck. Adding carbon fibre to the neck does not seem to produce any audible advantage whilst adding significantly to the build complexity".
Personally, I won't make a guitar neck of Cedro without a carbon fibre reinforcement. I've experienced first hand a Cedro neck made with a thickness of 21.50 at the nut, tapering to 23.50 at the 9th fret have more bow than a neck with the same dimensions reinforced with carbon fibre, the carbon fibre neck had almost no forward bow,in comparison to the un reinforced neck. Sorry no Data because there are far to many variables in the Cedro, ebony etc. besides I'm not a numbers guy.
Apparently, I'm not alone in this way of thinking, as Martian, taylor, Ramieriz, Bernabe, and countless others use reinforced necks as well. However if we listen to Trevor Gore there is absolutely no need for this is "reasonable wood' is used, whatever the heck that means.
Here Trevor passes off his experience and the ASA peer review panel as verification of his hypothesis, yet amazingly in the same paragraph he asks me for "DATA". Making ridiculous assumptions that I can pick out a carbon fibre reinforced neck from one that isn't. Hell.....I can't even pick out a spruce, or cedar guitar in a blind test, as gifted as I think I am, but that doesn't mean spruce sounds the same as cedar, we all know it doesn't. I think I would have better luck if I could actually play the spruce or cedar guitars and sink my nails into them a bit.Can't see any charts or numbers, so probably not data! But it is "the author's experience". The ASA (Acoustical Society of America) and their review panel didn't have a problem with any of that, and they're pretty data driven. I've measured and listened to lots of guitars, some with CF in the neck, some without. I've built guitars with CF in the neck (incorporated in various positions and ways) and many more without. I can't hear any difference that I can attribute to the CF, neither can I measure any feature in their sound spectral responses attributable to CF in the neck (...may explain the absence of data...) not in my guitars or anyone else's that I've been able to measure/listen to. Are you saying you can pick a guitar with CF in the neck in a blind listening test? Love to see your data if you can. Happy to be convinced.
Trevor also states he can't measure a spectral response attributed to CF. How Trevor can even claim to be able to measure, or not measure this on a completed guitar is mind boggling, considering the subtle differences in all materials and building techniques. Did Trevor make one guitar without CF, then take off the fingerboard and insert a CF reinforcement and perform his tests? I doubt it, and yet he claims to be able to do this, but, he demands data from the rest of us and expects us to just take his word for it.
Lets kick this around shall we? It will be great fun.
