Posted on July 28, 2026July 28, 2026 by Dale Phillips Review: Logistimatics Micro 299 Mini GPS Tracker Review: Logistimatics Micro 299 Mini GPS Tracker by John Mello Originally published in American Lutherie #143, 2021 Logistimatics Micro 299 Mini GPS Tracker logistimatics.com/shipping In the midst of the pandemic I shipped one of my guitars Next Day Air to a client in Chicago from my shop in the San Francisco Bay Area, by a carrier that will remain unnamed. Not only did it not get there the next day, but they lost track of it, finally delivering it a stomach-churning week later. Not wanting to feel quite so helpless when I needed to ship a second guitar to the same client via the same outfit, I, with the help of my more tech-savvy son, located and purchased the Logistimatics Micro 299 Mini GPS Tracker. At a mere 2 1/2˝×1˝×5/8˝, it slipped easily into the storage compartment of a guitar case. Setup was quite easy, and once I downloaded the app and turned it on, it reported its location hourly on a phone, tablet, or computer. Mine ran for at least two weeks on a single charge, and it should last up to five weeks if you adjust the report frequency.

Running time 14:38:25 Any beginner who has decided to start his building career with electric guitars simply because they are easier to make than acoustics has not thought their decision through very carefully. In the most simplified version of the electric guitar, they may be correct, but at the full-blown, detailed, professional level there are just as many considerations to approach as an acoustic instrument. This video set of 161 lessons teaches the construction of a Telecaster-style guitar with a bolt-on neck and a Les Paul-style guitar with a set-in neck and the full Gibson treatment.

Posted on July 15, 2026July 15, 2026 by Dale Phillips The $75 Guitar Challenge The $75 Guitar Challenge by Doug Hunt and Mark French Originally published in American Lutherie #142, 2021 Mark: A couple years ago, I was walking around a big home store and started to wonder whether it would be possible to build a guitar only from things I could buy there. Obviously, they didn’t sell tuners, fretwire, or truss rods. However, I thought it might be possible if one had those three things. I decided that, given those parts, it might be possible to make a guitar with $75 to spend at the home store. Thinking it might be an interesting challenge, I suggested the idea to Doug Hunt. Doug and I have been guitar-making friends for years, having met as part of a project aiming to teach technical subjects to high school students through guitar making. (Check it out at guitarbuilding.org.) He was interested, though not looking for one more thing to do at the time. A while later, he suggested that a better idea would be to start with a budget of $75 that could be spent anywhere (he’s a big fan of eBay, as it happens). As long as the money could be spent anywhere, he thought that it might be possible to do the whole instrument for $75. Over some months of occasionally revisiting the idea, we did a little negotiating and settled on the following rules: Become A Member to Continue Reading This Article This article is part of the Articles Online featured on our website for Guild members.

Posted on July 8, 2026July 8, 2026 by Dale Phillips Measuring Resonant Frequencies of an Acoustic Guitar Measuring Resonant Frequencies of an Acoustic Guitar by Mark French Originally published in American Lutherie #143, 2021 Many luthiers track resonant frequencies of their acoustic guitars, often with the goal of meeting some target values. It’s common for the first two resonant frequencies of a full-sized acoustic guitar to be near 100Hz and 200Hz respectively. Some builders use detailed frequency measurements during the build process. For example, Greg Byers described his methods in his 2017 GAL Convention workshop (AL#134). Another good discussion is in Volume 1 of Contemporary Acoustic Guitar Design and Build by Trevor Gore and Gerard Gilet. Resonant frequencies are a function of the ratio of stiffness over mass. Specifically, frequency is proportional to √(stiffness/mass). This simple relationship is harder to apply at higher modes, but it describes the effect of the structure on the lowest modes well enough for us. In practice, it’s easier to reduce resonant frequencies than to increase them. Selectively thinning parts of the top or shaving braces reduces stiffness more than mass, and so tends to reduce resonant frequencies. It’s very uncommon for luthiers to add anything, either mass or stiffness, to their guitars in order to modify dynamic response, though it is certainly a valid thing to do. Trevor Gore is the only one who comes to mind, though there may be others I’ve not heard of.

Posted on June 11, 2026June 16, 2026 by Dale Phillips Experiments in Audio Spectroscopy Experiments in Audio Spectroscopy by John C. Moore Originally published in American Lutherie #80, 2004 and Big Red Book of American Lutherie Volume Seven, 2015 R.M. Mottola’s interesting article in American Lutherie #70 (Big Red Book of American Lutherie Volume Six) described the use of audio spectroscopy, with a simple home setup, for the analysis of bass guitars. I had read about a spectrum comparison of a Martin D-28 with a Kaman AA 14-4 in An Introduction to Scientific Guitar Design by Donald Brosnac, and have always been intrigued with the idea of capturing in an objective way the “quality” of the sound of different acoustic guitars. Also, my experience has been that seeing colors of nature is enhanced by having tried to paint them, and tasting beer is enhanced by having brewed some. I felt that analyzing sounds from a guitar would heighten the senses here as well. When I read the Brosnac book, written in 1978, the equipment utilized for the guitar comparison sounded exotic and expensive, and certainly beyond the capability of the casual hobbyist. In Mottola’s article, it was clear that the technology of the PC had brought the potential for such experiments within reach. In fact, I already had hardware that could get me started: a digital camcorder that I could extract wave files from and a Sony Vaio laptop. So I decided to have a go at some audio trials.
