Gibson Banjo Information

Gibson Banjo Information

by Tom Morgan

previously published as Data Sheet #28, 1976



Recent popularity of the banjo and a need for wider dessemination of various bits of information have prompted this writing. Much of the information is based only on opinions formed during approximately ten years of experience working on banjos, while the instruments themselves were made over a period of 60 or more years. It should then be remembered that many variations are likely to have occurred.

During the years banjos have been manufactured, one strong contrast is noticeable. During the time of its wide popularity around 1920–1930, the tenor banjo was the style. The people then playing 5-string often makes it desireable to convert these.

Gibson banjos used a designation of RB for regular banjo of 5-string, TB for tenor banjo, MB for mandolin banjo, and so forth. Therefore, reference to a model-00, for example, should be understood to represent the different possible models that were, or may have been made (MD-00, RB-00, etc.)

The shell or rims were made to be an interchangeable basis for either of the different types, and a mandolin banjo can be converted to a 5-string banjo by installing a different neck. Problems in fitting may be encountered due to several shapes of the heel, and two sizes of lag screw (8-32 and 10-32 threads) being used. Also, shell diameters vary from about six inches in some banjo ukes to a 24 inch banjo bass. The most popular sizes were 10 1/2 and 11 inches, with the 11" size the only one well suited for upgrading with one of the better MASTERTONE tone rings.

Intonation in the Real World

Intonation in the Real World

by Mike Doolin

from his 2006 GAL Convention lecture

previously published in American Lutherie #92, 2007



Getting guitars to play in tune has been a major topic of interest for many years, both for guitar players and guitar makers, and it has been a major source of frustration as well. During our current “Golden Age of Lutherie” the bar has been raised for standards of craft, playability, and tonal quality, as players have become more sophisticated in their expectations and builders have become better educated and more demanding of their own work. Expectations for accurate intonation have come along with all that: it’s no longer acceptable for a guitar to only play in tune for the first five frets, or in a few keys. Modern players are using the whole neck, exploring extended harmonies, and playing in ensembles with other instruments. They are looking for instruments that play in tune with themselves and with the rest of the musical world.

It turns out that guitar intonation is a huge can of worms, because it is really two topics:

▶ What does it mean to be “in tune?”
▶ How do I make a guitar do that?

Constructing the Middle Eastern Oud, Part One

Constructing the Middle Eastern Oud with Peter Kyvelos, Part One

Here in the USA, interest in ethnic music of all sorts has seen an increase in recent years. Probably driven by immigration from many parts of the world and by the rise of so-called world music, this increased popularity manifests itself for us in an increased interest in the stringed instruments used in various ethnic musical styles. For instance, we’ve seen much interest lately in the oud, also commonly spelled ud or ’ud.

Starting off with absolutely no knowledge of a subject (as I did with this one), it is probably always a wise first step to consult the experts. Of course, with no knowledge of the subject, even the process of identifying subject-matter expertise is a problem, but I’ve always found that persistent and wide ranging investigation into just who the experts are is a fruitful approach. Eventually it becomes obvious that the same handful of names come up again and again in these queries. During the process of identifying those individuals most likely to be experts on the subject of the oud, it was both unusual and interesting that only one name came up repeatedly. Whether I asked musicians, luthiers, or academics, in this country or in the Middle East, the person that was universally regarded as the foremost expert on the oud was Peter Kyvelos. Working out of his shop Unique Strings in Belmont, Massachusetts, Peter Kyvelos has built close to 200 ouds and other Middle Eastern instruments. The shop, located in a section that is home to many Armenian and other Middle Eastern immigrants, also repairs pretty much all stringed instruments, plucked and bowed, domestic and foreign. But Middle Eastern instruments have been the focus of the shop and of the lutherie of Peter Kyvelos for the last thirty-five years. This dedication has earned Peter the reputation as the expert in this field. It has also earned him a National Heritage Fellowship from the National Endowment for the Arts in 2001.

Woodchopper’s Ball

Woodchopper’s Ball

by Bruce Harvie

from his 2004 GAL Convention Lecture

previously published in American Lutherie #90, 2007



How many people are here because they are thinking about processing their own wood? I highly encourage it. It’s very satisfying to build instruments from wood that you’ve cut. You can get a spruce on a firewood permit. It’s a great feeling to be out in the forest.

When the Guild was first starting out over thirty years ago, the word “tonewood” was not in common usage. Back then there were maybe only three or four suppliers. Now you can Google “tonewoods” and get a hundred suppliers.

There’s still a lot to be explored in the world of tonewoods. Englemann spruce didn’t really come on the market until 1978, and Red spruce not until ’89 or so. I can think of four or five species that are virtually untapped in the world of tonewoods: Noble fir, California red fir, and true white fir are all great woods. In Europe, you have places like the Ukraine opening up right now. They have beautiful spruce. I’ve seen quite a bit of it. We have wood here at this convention from the Balkans. That’s nice to see. It’s amazing how much wood is here. It’s just great to see all the guitar tops and woods for sale. And don’t miss the auction.

If you look at the woods that were used in guitars in the first part of the 20th century, you see some scuzzy looking wood. On some of the best-sounding prewar Martins, the tops are mismatched and the grain is running every which way. You see tons of runout because that wood was supplied in the form of lumber, not split billets. I see some wonderful-sounding old guitars that were built with wood that people would throw away nowadays. But a typical guitar store today has walls full of Breedloves or Martins with tops that were milled correctly, probably by Pacific Rim Tonewoods up in Concrete, Washington. They do an incredible job of milling guitar wood.

The Trio Romantico and the Requinto

The Trio Romántico and the Requinto

by C.F. Casey

previously published in American Lutherie #89, 2007



Picture it: You’re sitting in an open-air courtyard, perhaps in Guadalajara, perhaps in San Juan, perhaps in Buenos Aires. Your surroundings are lit only by the candles on the tables and the stars above. The air is like a caress on your skin. Across from you sits someone you care about very much.

Nearby, in the semi-darkness, a small group wanders from table to table. You hear voices in close harmony, singing in Spanish, singing of love. Two guitars throb in the rhythm of a bolero or a tango. And above, between, and around the words, a third guitar pours out cascades and arabesques of clear, shimmering notes.

As the song ends and the group moves on, you gaze through the candle light, deep into the eyes of your companion, and say:

“I’d love to get a closer look at that lead guitar; it’s got a really unique sound. Maybe I could get my inspection mirror inside it and get a look at the bracing.”

We can’t help it: we’re luthiers.

You were listening to the sound of a trio romántico, and the lead instrument was a requinto, a smaller version of the regular nylon-string guitar, tuned a perfect fourth higher (ADGCEA).
