Reading what Jim Soloway's post concerning Peerless, it got me wondering about the scarf joint. What is it's purpose? Why not just build the neck without it like most US manufacturers do?

I thought it was to cut down on costs and manufacturing time.
The headstock being one piece, without wings attached to the sides and the neck, 1 piece is then attached.
I don't see how an 'angle' makes sense, so if you could elaborate Dan, that would be great.

Well, Jim was in the business, so he probably has a good idea what issues the scarf presents, but I have owned both types of necks during my lifetime and I haven't noticed any practical difference between the two. Perhaps neck stability is better with a multi-piece neck as opposed to a single scarfed board?
As far as saving time goes, I'm not certain, as from the lutherie books I've read and videos I've watched, you have to cut the neck stock on the correct angle, reverse the cut stock and glue it back together. I know that in wooden model building this produces a stronger joint, but I have no experience building necks yet. Perhaps the time savings is in using a single piece of material rather than building up a profile neck?
Most of the scarfed necks I have read about or seen being built in videos are also made from a single piece of material, not a built-up laminate of 3 or 5 pieces of wood to the correct neck thickness plus overage (which I would imagine is a more stable design as you can run the grains against each other to help avoid twisting (I believe, based on what I have read about the process).
Scarfed or built up from profiles, I still see the "wing" pieces being glued to the headstock. I don't think it would be cost-effective (in material and/or labor) to build up a multi-piece neck the width of the headstock and then reduce the excess material not needed. Again, this is all just speculation based on reading and observing with a thought towards actually building one day. I have no actual experience yet.

1. It can be cheaper to build a neck since you don't have to use as thick a piece of wood.
2. The scarf joint allows the grain of the headstock and the area where the head meets the neck to be oriented parallel with the headstock face. Some maintain that this makes the neck stronger in this area, some disagree.
3.I have guitars with both types and they're both fine. The single piece of wood does look nicer, to me.
-
The difference is not really one of function but rather, much like other budget or luxury features, one of a more symbolic statement. A scarf joint (along with a glue on heal) dramatically reduces the cost the materials in the neck. I've had several necks made that way and they all functioned just fine but unless they are done in a very elaborate manner, they say to the customer that efforts were made to contain cost. It's not unlike other features like multi-ply binding and purfling, intricate inlays, and heavily figured wood. None of those have a functional value, but they are all part of the luxury package that most people associate with a high end guitar.
-
@Jim - OK, thanks for the reply. I personally like a simple, unbound instrument, no inlays, nothing fancy, so I guess I've never thought about it from that respect. Interesting.
-
I dunno, it just seems like an unnecessary step to chop up two pieces of wood just to glue them back together for a neck. Wouldn't it be simpler/cheaper to just carve a neck out of one piece and be done with it?

The headstock changes the angle of the piece while the grain orientation stays the same. The scarf joint solves this problem. Like so:
This short-grain issue, coupled with a deep groove for the truss-rod nut, is the reason behind the classic Gibson headstock break:
Having their headstock held on by glue tends to make people nervous, but most modern wood glues (and some not-so-modern ones) are much more stable than the wood itself.
As far as simpler/cheaper goes, it is pretty easy to make a saw cut and brush on some glue. I would rather do that than scrap half of my available neck wood.

Like anything meaning a cost saving for the manufacturer, it is a matter of weighting the pros versus the cons in the end.
In my book, a thinner stronger and less prone to warp neck is a positive thing and should not mean necessarily a bad thing.
It makes these instrument less desirable, but without opening a can of worms that remain again a very subjective topic...
-
So, correct me if I'm wrong:
It seems like the advantage of the scarf joint is that it's cheaper and stronger.
While the advantage of the one-piece is that it's more expensive and weaker?
If so, give me scarf!
-
lots of very expensive classical guitar necks are made with a scarf joint and stacked heel.
a neck blank for a one piece-neck could yield 2 or 3 necks with scarf joints.

There are quite a few non-bargain guitars (mainly classical, but also, e.g., some Taylors) that have this. But there's also the style found on many cheaper guitars, especially Korean ones (proud Samick owner here), where the joint is at around the third fret. This is strictly a cost-saving feature enabling the maker to take two short pieces and join them into a neck/heastock. It works fine, but the joint is obvious with lighter finishes and not terribly attractive IMO. My Samick is more than 20 years old, and shows no signs of falling apart.

Scarf joint necks aren't new; they've been around for a long time and it's a proven construction method.
If you accept that a scarf joint neck is mechanically sound and possibly better than a one piece neck in terms of stability and robustness (all other things being equal), the only remaining negative aspect is the perception : scarf joint means cost saving technique which means cost saving techniques may have (probably have) been applied to the remainder of the guitar construction which implies it's an inferior guitar. It may not be inferior at all, but the perception can be there because of it.
No question that with a one piece neck, you've paid for a pile of wood that you never got; it all ended up in the scrap bin.
-
I can see why they are not popular...
Certainly not the most desirable thing on an aging natural guitar esthetically wise...
Here is a shot of my 2003 Peerless Regent : with the flash of the camera it is even worst : no doubt about its presence !
However, that neck is the best I have ever played; dead straight and I could achieve such a low action with the 15-56 it plays like a charm.
The laminated neck on my Joe Pass while also being very comfortable, doesn't feel as great as the one on the Regent.Last edited by vinlander; 10-17-2014 at 03:11 PM. Reason: precision addon

The whole discussion leads to something I've long considered an interesting question: does perceived value in guitars have more to do with fashion rather than function? I certainly think so but it's a tough trend to buck. I remember in university economics studying a phenomenon known as the water vs diamonds paradox and I think that applies very well here

Buy or don't buy, I don't think the way things work are going to change just because folks like you and I don't like it. We're not even a drop in the ocean. We're just consumers with a choice. Just my opinion.

These rules determine what may be called the relative or exchangeable value of goods. The word VALUE, it is to be observed, has two different meanings, and sometimes expresses the utility of some particular object, and sometimes the power of purchasing other goods which the possession of that object conveys. The one may be called "value in use;" the other, "value in exchange." The things which have the greatest value in use have frequently little or no value in exchange; on the contrary, those which have the greatest value in exchange have frequently little or no value in use. Nothing is more useful than water: but it will purchase scarcely anything; scarcely anything can be had in exchange for it. A diamond, on the contrary, has scarcely any use-value; but a very great quantity of other goods may frequently be had in exchange for it.[3]Furthermore, he explained the value in exchange as being determined by labor:
The real price of every thing, what every thing really costs to the man who wants to acquire it, is the toil and trouble of acquiring it.[4]Hence, Smith denied a necessary relationship between price and utility. Price on this view was related to a factor of production (namely, labor) and not to the point of view of the consumer.[5] The best practical example of this is saffron - the most expensive spice - here much of its value derives from both the low yield from growing it and the disproportionate amount of labor required to extract it. Proponents of the labor theory of value saw that as the resolution of the paradox.
The labor theory of value has lost popularity in mainstream economics and has been replaced by the theory of marginal utility.Last edited by Jim Soloway; 10-18-2014 at 10:39 AM.

For me, looking, touching, is all part of the joy of playing archtops.
When I get excited by good art or beautiful craftsmanship, it gets my creative juices going, sort of like inspiration/muse I guess.
As much as I love the playability of my AF-120 (Scarf neck) the guitar in general leaves me feeling cold and creatively less inspired. Not saying I couldn't make great music on a cheap or ugly guitar but you don't get that same collision of artist inspiration or emotion.Last edited by ArchtopHeaven; 10-18-2014 at 11:13 AM.

The availability of high quality wood for musical instruments is diminishing- some classic woods are either prohibitively expensive, no longer available or heavily regulated because of over-harvesting. Luthiers compete with furniture makers, architectural wood uses, etc. Access to some woods is really, really tight now- ebony is one example, some of the mahoganys and rosewoods are others.
Sustainable Ebony | Taylor Guitars
Using that wood judiciously and conservatively seems to me to be a wise choice- using the scarf neck design there is a huge reduction in waste compared to a 2/3/4/x laminated neck. I think that combination wood and synthetic tops and backs- such as double tops with ultrathin wood veneers over Nomex or something similar will be the standard within a decade or two in archtop and flattop acoustic guitars. There's an interesting video documenting Andersen building a double top laminate, with a little commentary from Bill Frissell playing it.
Steve Andersen's Double-Top Archtop | The Fretboard Journal: Keepsake magazine for guitar collectors
Luthiers are going to have to become even more creative than they already are to continue to produce fine instruments in a world where the raw materials have been heavily exploited for centuries, in some cases, and will be harder to source and more expensive. As in agriculture, metals and energy, sustainability is becoming more and more important as the human race approaches 8 billion humans (which exceeds our ready natural resources but a whole lot, especially as a higher percentage develop energy-intensive lifestyles), perhaps 30-50% of species heading towards endangered status, etc.
The Extinction Crisis
One of my very favorite and best-sounding guitars uses a scarf joint mahogany neck, probably not for sustainability reasons per se but for headstock strength and less waste of wood- which is no doubt helpful to small luthiery shop.

With the state our planet is in, it somehow seems unethical to produce a one piece neck knowing the volume of wastage involved. This is especially so when a 3 piece neck is more stable. There are numerous great players out there who play guitars that do not have one piece necks. The point is that a one piece neck does not add anything either structurally or acoustically to a guitar....if anything, it detracts. It all comes down to the 'snob' factor from the individual demanding it.

If you personally feel a one piece neck sounds better, then you have better ears than me! If you feel it helps you to perform better, then by all means curtail your choice by only opting for guitars with one piece necks.

Besides the looks and tradition department, the presence of a scarf joint for me would add two more things to worry about, the long term stability of the neck, and the actual quality of the scarf joint. How would you feel about say a guitar with a broken and repaired neck? I don't have enough experience to have an opinion on its sound contribution, but having a choice I wouldn't bet for the scarf joint. Also since it is mainly used in cheap and middle priced guitars, it would be a sign of where the instrument belongs in terms of quality. I would rather trust the well known professionals in their opinion about it, and they all chose not to use it unless pressured by cost or wood sparsity (the exception being the classical world, but that's a completely different construction and tension thing).
Of course times are always changing, and instrument manufacturers have to comply, whether we are taking scarf joints, synthetic woods, waste, considering competition, quantity vs quality, etc. But reality forced choices and quality choices don't always coincide..
And it DOES also come down to price point. If you want to charge thousands of dollars for a guitar, wood has to sound good but look good also. Binding will be more elaborate, inlays fancier etc, it makes sense.
-
the classic broken Gibson headstock occurs in 1 piece necks often, because they are weaker in that area than necks with a scarf joint.
-
The scarf joint is needed if you have a 4/4 board of nice mahogany and you want to make a neck from it. To make a neck for an acoustic you will need to stack and join a few layers for the heel also. A well made neck with a scarf joint is likely to be stronger than a one piece neck.
If you have a 4/4 board that is flatsawn, then a 3 piece laminate is a good choice. The three piece laminate is also likely to be stronger than its one piece counterpart.
This is a good way to use stock that has already been cut down to 4/4. It depends on the species but some wood is hard to find in the wide widths needed for a one piece neck. I should mention it is faster to build a one piece neck.

We can debate whether an angled headstock improves tone of course and we will have few models to compare because most Builders are copying Fender who is copying itself and others are copying that ...lol.
But it IS was a way to save lumber and save labor .
Less obvious to many because it's so common and Strats and Teles are low resonance Guitars anyway ...generally.
But IF a Guitar sounds and plays how you want it to or expect it to...scarf joint and string trees etc are tolerable.
Suposedly glue joints are stronger than the wood but I wonder about that Joint and I wonder about Luthiers using the same Glues from 50 years ago
aiming to recreate rather than go beyond ...and if that joint will break easily ..
I think you're analogy to a broken and repaired neck is a good one ...kind of bad for a scarf joint .
But some of those Peerless sound and perform way above their price point .
I might take a chance on one for sure...

Is anyone here willing or able to post images of a scarf joint that failed?

I think it's cool that most experienced Jazzers on here love their Vintage Gibson's etc. but are first to admit when some inexpensive model plays and sounds way above it's price class...
-
Don't forget almost all guitar necks are made from more than one piece of wood. If you count the fingerboard. In fact the best necks are often multi piece necks. When you laminate a neck it is like plywood in that it is more stable than a single piece of wood of equal size. The problem with many necks with scarf joints is that you can see the joint. It is possible to completely hide a scarf joint under the headplate and rear veneer on a neck that uses them.
-
@Matt Cushman...
True the necks with longitudinal strips glued together
lengthwise ( redundant to be clear ) especially on softer woods like Mahogany and on Basses are said to be stronger and stiffer and need fewer truss rod adjustments...
I have asked ...but only know what Luthiers and end users with one piece and multi piece necks have said
multi piece longitudinal joint multi piece necks are more stable .
