Evan Gluck   Larry Fitzgerald                                                                                       

▪ Gluck is a beloved repeat presenter at GAL Conventions. This time, he brought along veteran New York repair guy Larry Fitzgerald. In addition to demonstrating fret-leveling techniques, they tell war stories of maneuvering their businesses to survive the recent global pandemic. Mentions Matt Brewster, Sam Ash, John Suhr, Rudy Pensa, Mandolin Brothers, Dan Erlewine, John Patitucci, Flip Scipio, LeRoy Aiello.

Cheap and Easy String Testing

▪ Ya talk about rabbit holes. Research into guitar intonation just gets deeper and deeper. This article homes in on individual string compensation at the nut, plus small adjustments to the position of the 1st and 2nd frets. Industrial strength data collection. Heed the eggheads.

Fret-Buzz Detector

2023
AL#150 p.54               
John Kruse                                                                                           

▪ Like you might have heard, it is possible to locate a buzzing fret on a guitar that uses metal strings by exploiting the fact that an electical connection would be made when the string briefly touched the fret. It can be hard to see a flickering light or see a response on a VOM. This little project is optimized to make that contact visible and audible.

Basic Steel-String Guitar Action Setup

2022
AL#147 p.24               
Robbie O’Brien                                                                                           

▪ Lutherie uber-pedagog Robbie O’Brien has taught beaucoup guitar makers and repair techs to set the action of steel string flattops, so his thoughts on the matter are crystal clear. Here he steps us through the process in a relaxed, logical, and concise presentation. From his 2017 GAL Convention workshop.

Guitar Evolution’s Missing Link: The Early 5-String

2022
AL#147 p.28               
James Buckland                                                                                           

▪ Baroque guitars were 5-course instruments. That is, they had ten strings in five pairs. Then suddenly here comes the 19th century and guitars had six single strings. Yadda yadda, now it’s today and everything is normal. The real story is a lot more interesting than that and it actually involves a “missing link;” the 5-string guitar. Luthier, guitarist, and scholar Buckland lays it all out for us.

An All-American 7-String Guitar

AL#146 p.38               
Lee Herron                                                                                           

▪ Sometimes you get a customer who just wants you to run wild. Check out the design and build process of this 17.75-inch, 7-string, multiscale black-locust flattop guitar. Fun!

“Restomodding” Wall-Hanger Guitars

2021
AL#144 p.6               
Roger Haggstrom                                                                                           

▪ A hundred and some years ago, Swedish folks sat around the house all of a dark winter and sang hymns together, accompanied by the strummings of cheap mass-produced guitars. Those days are gone, but a lot of the guitars are still hanging on the walls of old houses. Roger Häggström has made a business of restoring them to useful condition and modifying them to sound and play better than they ever could have. He restores and modifies. Restomods. Mentions the Levin guitar company.

The Terz Guitar

2021
AL#142 p.30               
James Buckland                                                                                           

▪ The terz guitar was a smaller Romantic-era guitar, which played in a higher range and was written in a different key. Knowing this history helps us understand several otherwise-puzzling old instruments.

Tuning a Marimba Bar and Resonator

AL#142 p.55               
Max Krimmel                                                                                           

▪ If you are luthier who does not remember the name of Max Krimmel, you might be under age fifty. Max was a pack leader in the early days of the American Lutherie Boom, before he went on to specialize in a few of his many other artistic interests. Anyway, why and article about marimbas? As Max says, “Think of it as deep background learning.”

Resurrection and Modification of an Inexpensive Old Factory Guitar

2019
AL#138 p.48               
R.M. Mottola                                                                                           

▪ Sometimes when a vintage instrument is being restored, you want to leave a few of the dings and a lttle of the funk, just for authentic flavor. Sometimes you want to leave the big dings and all the funk, and end up with something that is very tasty to a certain sophisticated palate. Mottola takes a century-old beater and ends up with a sweet-playing silk purse disguised as a sow’s ear. Mentions B&J, Buegeleisen and Jacobson, Oscar Schmidt, and Stella. Instrument is ladder-braced.

Delrin Frets

2019
AL#136 p.52               
Harry Fleishman                                                                                           

▪ Many years ago, innovative classical guitar maker Richard Schneider made instruments with frets made of rod stock set in wide saw kerfs. Fleishman updates the idea by having round-bottomed slots cut by CNC and laying in Delrin rod.

Letter to the Editor: Just Intonation Fret Layout

2019
AL#136 p.3               
John O’Sullivan                                                                                           

▪ Guitars don’t always have twelve equally-spaced frets per octave. They almost always do, but not always. Here’s another take on the possibilities, ccalled Eagle 53, which attempts to come closer to the beautiful dream of just intonation.

Measuring Scale Length of Fretted Instruments

2019
AL#136 p.48               
R.M. Mottola                                                                                           

▪ What’s the scale length? Isn’t it just twice the distance from the nut to the 12th fret? Yeah, kinda, but there can be a lot of complicating factors when working on old instruments. Like maybe the nut position was compensated, or just cut wrong. Or maybe the 12th fret was a little off. The fret positions might have been calculated using the old rule of 18. Here’s how to find out what’s really going on.

The Pretty Good Setup Tailpiece

Jay Anderson                                                                                           

▪ Here’s a simple device that lets you string, play, and set up a flattop guitar before you glue the bridge on.

An Adjustable Compensating Guitar Nut Design

Paul Eliasson   Orn Eliasson                                                                                       

▪ Relax. The clunky Frankenstein of a nut in this photo is not the design to which the article title refers. The Eliasson design is sleek and compact.

Letter to the Editor: Guitar Compensation Experiment at 2017 Convention

2017
AL#132 p.3               
R.M. Mottola                                                                                           

▪ Mottola collected some data about string length compensation at the 2017 GAL Convention. He promises to publish soon.

Classical Guitar Setup

Kevin Aram                                                                                           

▪ Kevin Aram has long been one of the very top classical guitar makers in the United Kingdom. Here he takes us through his process of setting the action on a classical guitar and making sure the frets are shipshape and Bristol fashion.

A Field Guide to Mandolins

2017
AL#132 p.30               
Graham McDonald                                                                                           

▪ Mandolins have come in a wide range of sizes, shapes, and styles in over 350 years of history. And while you are not likely to stumble upon the kind of mandolin that Vivaldi wrote for, you may find yourself looking at a century-old American factory-made cutie like this Smurf-head Regal, resplendent in muliple pearloids. This article gives you a quick introduction to the rich diversity in the great Family of Man(dolin).

Let’s Catch Up With Graham Caldersmith

2017
AL#132 p.44               
Juan-Oscar Azaret   Graham Caldersmith                                                                                       

▪ Graham Caldersmith’s articles in GAL publications go back a full thirty-five years, earlier than American Lutherie magazine itself. He’s located in a tiny town in the hinterlands of New South Wales, Australia. He uses his scientific training to develop innovative classical guitars, and has long been a leader in the effort to develop a family of guitars of different sizes and musical ranges. Our globetrotting reporter asks about his latest thoughts and methods, which include carbon-reinforced lattice bracing.

A Better Approximation to the Rule of 18

2017
AL#132 p.62               
Mark French                                                                                           

▪ We think the old boys found the 1st fret position by dividing the string length by 18. Then they divided that by 18 to get the 2nd fret. Sounds like a job for that nerdy apprentice kid. But 18 is just an approximation of the “right” number; that is, the 12th fret won’t be right in the middle of the string. If you want to do it by hand, here’s some thoughts and numbers about what would be a better approximation, and how much better it would be.

Techniques for Guitar Repair Efficiency

Erick Coleman   Evan Gluck   Eron Harding                                                                                   

▪ Erick, Evan, and Eron called this workshop “Making Bread with Bread-and-Butter Repairs.” Their emphasis was on tools and techniques to help you get a lot of the usual repair jobs done in a short time and at a high level of quality. from their 2014 GAL Convention workshop.

Google Calculator and the Guitar’s Magic Number

▪ Did you know that the Google search engine has a calculator? This piece is a math lover’s dream. There’s lot of formulae. The goal is to lay out a fret pattern for any scale length, then find the perfect intonation point for it. You’ll need a pretty good guitar tuner to take advantage of the process. All you math challenged luthiers out there, just say “Duh. . . .”

▪ The author begins with a lengthy introduction to explain why guitars can’t play exactly in tune in every key, all the way to the point where music theory clashes with physics. It’s pretty deep but it’s fun. The cure for wayward guitars is to find what music a guitarist plays the most, and then adjust the action and intonation at both the nut and the saddle to find the most satisfactory compromise for that player. This is the thinking luthier’s approach to intonation correction. With 4 charts and a drawing.

Product Review: Stewart-MacDonald Fret Scale Rules

2006
AL#85 p.59               
Harry Fleishman                                                                                           

▪ Fleishman is at his humorous best here, hunting the past for how frets used to be laid out, why they were often wrong, and why the new Stew-Mac rules are tools worth having. Did you know there are at least three ways to calculate fret spacing? Did you know they vary in their results? Can musicians hear the difference? With 1 photo and a chart.

Restoring Tarrega’s 1888 Torres

Jeffrey-R. Elliott                                                                                           

▪ Restoring famous instruments is a tricky business. If they are also old, well-played, and abused by poor storage facilities the work becomes a cross between knowledge, craft, and art. Elliott goes where few of us would care to travel, explaining every step of restoration as he goes. Perhaps as important is what he doesn’t do. The ethics of restoration is a foundation of the story. With 42 photos as well as a 2-page spread of GAL full-size plan #52.

Questions: Saddle Compensation for Octave Mandolin

2005

John Calkin                                                                                           

▪ Rule of thumb information on saddle compensation for an octave mandolin with a 560mm scale and fixed bridge.

A New Look at the Chromatic Dulcimer

1999
AL#59 p.36   BRB5 p.390            
Merv Rowley                                                                                           

▪ Rowley may have been the first to use metal rod for frets rather than fret wire, a technique often attributed to Richard Schneider. He has built dulcimers for many years and has been something of an innovator. Here he examines the chromatic, rather than the diatonic dulcimer, and decides that perhaps it’s time has come and how to make it most acceptable to those who already play the conventionally fretted instrument. With a photo and two charts.

Making Compensated Saddles

Jeff Huss   Mark Dalton                                                                                       

▪ Hand carved and compensated bone saddles are a mark of finesse. Fine work is all about the details, and Huss and Dalton discuss a detail that is often overlooked but easy to make. With 8 photos.

Meet the Maker: Paul Jacobson

AL#55 p.48   BRB5 p.243            
Cyndy Burton   Paul Jacobson                                                                                       

▪ Jacobson is a widely respected builder of classical guitars who considers lutherie to be the equivalent of writing sonnets. They are both exercises in controlled creativity. And both can be beautiful.

▪ The kabosy is a folk instrument from Madagascar. It comes in several body shapes, but always has a neck with the same layout of staggered frets, many of which don’t completely cross the fingerboard. It’s easy to build and fun to play once your eyes stop being baffled by the weird frets.

Taking the Guitar Beyond Equal Temperament

1992
AL#30 p.46   BRB3 p.210            read this article
Don Musser                                                                                           

▪ Musser tries to get the guitar to play in tune with itself by laying out the frets for just intonation, rather than equal temperament. Interchangeable fretboards allow the changing of keys and tunings. Pretty interesting, and the new fret pattern looks very bewildering and cool. Based on the work of Mark Rankin.

▪ Nearly every person alive in the western world has grown up with music that sounds the same in every key, but there was once a time when music had no keys, and later a time when each key had its own particular sound. We are perfectly comfortable with how our music sounds, but are we richer for it? More importantly, people once had different concepts of music, and perhaps different expectations. They thought differently. And if they thought differently about music perhaps they thought differently about everything. How can we understand their times if we can’t understand the way they thought? Kottick doesn’t delve into this, but you might be tempted to after reading this article.

Hammered Dulcimer Tuning Tricks

1983

▪ Some of these tricks need to be built into the instrument. The others are useful after it’s complete. With hammered dulcimers you need all the tuning help you can get. With 5 drawings.

Tuning the Guitar

DS#45   BRB1 p.288            
Ian Noyce                                                                                           

▪ ‘Bet you thought you knew how to tune a guitar. Some are fussier than others, right? Noyce explains that fussiness, and by examining the fussiness it can in part be designed out of the guitar. On the other hand, part of the problem is psycho-fussiness, meaning that you have to tune to suit the peculiarities of human hearing. They say that horses have perfect pitch, so tuning up must be much less of a chore for them.
