By May of 1922, fittings, such as tuners, tailpiece, pickguard, case, and even strings were of prime consideration. Style F-4 had been the flagship of the Gibson Mandolin and Guitar Company since the first listing of models in the 1903 catalog. Now, the look of style 5 must be distinguished from style 4. In the Guild Convention, in the press, and more importantly, in sales, Gibson’s prominence as the leader among musical instrument merchandisers had been seriously challenged. Model F-5 was their answer, intended to attract national attention as an astounding upgrade in sound, finish, construction and playability. Clearly, the fittings must reflect a status befitting the “top-of-the-line” Master Model.
Pickguard or finger rest: Since 1909, Gibson had demonstrated the benefits to tone and volume from elevating the pickguard above the mandolin sound board; style 5 would be updated and upgraded yet again.
Geared tuning machines: Beginning as early as 1904, the Louis Handel Company of New York supplied Gibson with geared tuning machines. Handel tuners can be identified by the characteristic wavy-end base plates and in the more expensive versions, tuner buttons with delicately inlays: four silver wire branches terminating in gold-leaf finials emanate from the center, a tiny pearl inlay of various shapes including dot, diamond and bird. Labor shortages for Handel in 1918 greatly slowed production, and by 1923 they were out of business.
There were reasons other than the loss of supplier to redesign mandolin tuners. “Tone color is determined by the number, identity and proportion of the overtones or partials present in the tone of the instrument…The further away the overtone is from perfect consonance, the more richness and less brilliancy the overtone adds” (“A Talk About Tone,” Lloyd Loar, Master Model foldout leaflet). Placing the tuner plates so that all the strings are free to vibrate between the nut and tuner post would also contribute to Loar’s definition of richness. To achieve this, new designs would be required. The solution for the A model was the “snakehead” peghead.
The transition to new geared tuners was more complicated for the F-5; it took almost a year for the various problems to be resolved.
From 1904 until 1923, the measurement from center to center of the string post for the tuners on all Gibson mandolins was approximately 15/16. By the summer of 1923, this distance was shortened to 29/32, resolving the problems; inlays were not violated, plates did not overlap, all buttons were free to turn and the strings were free to vibrate from nut to string post.
Strings: Wound “The Gibson” strings were spun with Monel, an alloy of nickel and copper, with over 50% nickel, less than 50% copper and small elements of iron, manganese, etc. First created in 1905 by Robert Crooks Stanley while working for the International Nickel Company of Toronto, Ontario, Canada, Monel was based on the same proportions of nickel and copper found naturally in meteoritic nickel ore from the Sudbury mines, also in Ontario, Canada. Monel was an attractive alloy for many uses because of its resistance to corrosion. By 1923, Gibson released a set of strings whose winding consisted of an alloy that replaced most of the copper with silver, advertised to give a “more lustrous sheen and sound.” Gibson also advertised a set with unwound stings of an alloy with a high percentage of copper.
Of course, no Master Model mandolin would be complete without the “Faultless" plush lined case by Geib snd Schaefer of Chicago, Illinois.
