It’s All About the Core or How To Estimate Compensation

It’s All About the Core

or How to Estimate Compensation

by Sjaak Elmendorp

Originally published in American Lutherie #104, 2010



Ever since I started playing guitar, I’ve wondered why the saddles in my steel string guitars were set at some magical angle and, more puzzling, why the B string in my Martin D-28 (well, a cheap Japanese replica I have had for forty years now and still outbooms any guitar you want to bring to the bonfire) was about 10% sharp. After having accepted that this was one more quirk of the guitar-building community I had since joined, I got intrigued again when I set out to build a long-scale nylon-string acoustic bass (Photo 1) and, for the life of me, didn’t know what compensation to use.

The physics of the problem is very straightforward, but I found the mathematics employed to date rather inaccessible and the recipe for applying the developed theoretical frameworks not very clear. Given the fact that I once was a practicing physics PhD, I had to assume I wasn’t the only one wrestling with the question. Over the course of a long e-mail conversation with R.M. Mottola, for which I am very grateful, I was beginning to see some light at the end of the tunnel.

Reflections on my Career

Reflections on My Career

by J.R. Beall

Originally published in Guild of American Luthiers Quarterly 6, #1, 1978



This year of 1978 will mark my tenth anniversary as a practitioner of the luthier’s art. Those of us who have engaged in any profession for a longish period of time like to think that we have gained insight regarding that profession and, though such an assumption may be debatable, there is no doubt that we are more than willing to give advice to all and sundry who will listen. Being no less human than the rest and having evolved, over the years, the motto that, “Tis better to bore than be bored,” I shall proceed herewith.

A decade ago, we were considerably fewer in number. There was, of course, no G.A.L. and much less information about the craft. Sloane’s first book, Classic Guitar Construction, had just been released and it was a real boon to many who were trying to make a beginning. I built my first guitar with only a copy of “Guitar Review” No. 28 as a guide. I wasn’t really such a bad set of instructions, but it wasn’t meant as a how-to-build essay and much was missing. At any rate, most of us know what a tremendous thrill that first guitar is. To actually hold in one’s hands the result of so much thought and effort, to experience the consummation of a truly difficult and challenging creative act is, in a very real sense, a personal triumph. Most of us will look back on that first instrument with some embarrassment for its crudity and its faults, but no matter how skilled or accomplished we may become in subsequent years, the completion of that first “#1” is an all time high. I have built only about fifteen guitars during my career. I find them to be the most difficult of all the instruments I have attempted and financially comparatively unrewarding. It has been my observation that to become a truly competitive guitar builder, one needs to have built something like a hundred instruments or had a truly excellent teacher. This is not to say that the first one hundred guitars may not be very good and quite saleable, but only that the complexity of the task requires a very long and arduous apprenticeship. The unfortunate part is that usually, after half a dozen or fewer instruments, most of us feel that we are professionally ready for the market place. We fantasize glorious and financially successful careers and many make major changes in their lives to accommodate this new vocation. After another ten or fifteen guitars, the realization begins to dawn that we know very little about this very complex and sophisticated instrument and, what is even more discouraging, that we are probably unable even to achieve as good a finish as is common on commercial instruments selling for $200–$300. Our biggest problem is that no one has explained that there is simply no substitute for serving one’s time. The construction of a guitar in the Ramírez, Kohno, or Martin steel string class requires at least much knowledge and experience as is necessary of a candidate for a PhD. in any of the professions and the time requirement must be roughly equivalent as well. If one is willing to give seven or eight years to the learning process and has a sufficient natural talent as well, the glories and riches of the master luthier may be attained... but no less will do. I don’t mean to discourage those earnest aspirants to the luthier’s art, but only to inject a realistic note. I know, personally, several master luthiers. I know a great many guitar builders, but only a few who are truly competitive with the “name brands” and they have all served their time. Most of the successful ones became that way because they were driven. They have worked long and hard to achieve true quality. It seems to me that of late I have encountered more and more would-be luthiers, particularly dulcimer makers, who have taken up the craft as a means of avoiding an ordinary job or profession. Needless to say, such people have a somewhat more casual approach to building and it can be predicted that they are not likely to become professional. It is impossible to stress too strongly the necessity for a professional attitude toward what we do!

On-Board Preamps

On-Board Preamps

by Bob Meltz

Originally published in Guild of American Luthiers Data Sheet #158, 1980



Seeing that I, like other luthiers, enjoy the finer things in life (i.e. food, clothing, shelter), it is always a pleasure to find something that a) provides the luthier with a good return on his investment in time and materials, and b) provides the customer with something useful at a reasonable price. Such is the case with this little tidbit.

It happens that most of my clientele play electric instruments and I have implanted preamps in dozens of these instruments with universally good results. It seems that most electric guitarists playing rock, fusion, or contemporary jazz are endlessly searching for ways to provide them with the sound of small, overdriven tube-type amps. The most common device used to accomplish this is the “distortion box” as made by a number of companies. The disadvantages of this type of device are numerous: a clumsy box sitting on the floor with cords dangling at the feet of the player, added noise from all but the most expensive units, line loss when the effect is bypassed, etc. For all but the people who are looking to totally “raunch out”, the on-board preamp is a viable, indeed preferable, alternative. Although it provides practically no distortion of its own, the added output is enough to overdrive the preamp stage of almost any guitar amp.

Spraying Lacquer With Nitrogen

Spraying Lacquer With Nitrogen

by Harry Coleman

Originally published in Guild of American Luthiers Data Sheet #64, 1978 and Big Red Book of American Lutherie Volume One, 2000



There are several advantages of using compressed nitrogen for spraying over the more conventional air compressor. Air compressors, when pulling air right out of the atmosphere, also pull the moisture in the air right into the storage tank. Most of it can be filtered out, but not all. In addition, oil has a way of working its way from the piston assembly in the compressor into the air line and ending up on your work. Compressors are expensive and do break. You have to have a long enough air line to get the compressor out of the finishing room or a spark from the motor could blow you away. Long lines cause a drop in air pressure.

With nitrogen you are assured of 100% clean, dry “air.” Since there’s no motor involved, you can put the whole unit in the finishing room and use a shorter air line. The only disadvantage is that air is free, but nitrogen isn’t. You also have to take your tank out to get it filled. This is inconvenient, but the quality of the spray job makes it worth the trouble and expense, especially for a low-volume shop.

Art As Adventure

Art As Adventure

by William Eaton

Originally published in Guild of American Luthiers Quarterly Volume 10, #3, 1982



Dear Fellow Luthiers — Guild Members,

If I could hold a pen as a chisel and feel the inspiration and enjoyment that comes with instrument building and music I think it would take few words to express myself. Surely the power of words and thoughts reaches everywhere for those with open reception — all in time — and so my communication with you — if not from words — then from a common interest for buiding and repairing musical instruments. For the musical instrument becomes a magical messenger to voice the sound of its being — in all ways and all forms, for all to play and listen — in all styles. The builder and restorer of the instrument holds a noble role in the adventure of human action, if we are to perceive our activities with purpose — the bringers of music, the singers of music. For the instrument is born before the musician — except for the hallowed voice, the instrument of the body.

I truly look upon this art as an adventure. To envision music — to imagine a new instrument — to build the instrument — to play upon strings — this makes me sing — to conplete the whole — from imagination to manifestation.
