1932 Epiphone Masterbilt Advert

Close-up #40: Reconstructing the 1931 Masterbilt model lineup

"In June 1931, the firm officially announced its already-established line of Masterbilt guitars." Since author Tom Wheeler had stated this information in his groundbreaking 1982 book “American Guitars”, it has been requoted by countless guitar historians and journalists in books and magazine articles.

But – strangely – we have never seen any official Epiphone letter, flyer, advert or similar official document about this historically important 1931 product announcement. (If you have, please let us know!)

Well, there is a Masterbilt flyer which some historians (Gruhn, Carter, Fisch/Fred) had dated to the year 1931. However from what we know today, it is clear that this flyer was actually published significantly later – probably in early 1933. Some evidence for this claim:

The earliest Masterbilt-related advert we are aware of was published in the February 1932 issue of "Metronome" magazine.

Therefore, the first Masterbilt catalog – published at some point in 1932 – is the earliest official source that offers a detailed overview of the Masterbilt product line. However: The model info presented in that catalog of course doesn't necessarily mean that the instrument lineup and features were the same at the launch one year earlier, in June 1931!

So how can we find out what models Epiphone had launched in 1931? Let's try to assemble the puzzle pieces of what we know, with the goal to reconstruct the initial 1931 Masterbilt lineup – taking into account two sources of information:

a) Surviving instruments with low serial number (< SN 5400):
We assume that the Masterbilt series started with SN 5000, and we estimate it reached approximately SN 5400 by the end of 1931. The lower the SN of the documented examples, the higher the probability that the models were part of the initial lineup.

b) Product images from 1931 used in later catalogs:
Of some Masterbilt models listed in the 1932 catalog we haven't been able to trace any examples with a SN from 1931. But we noticed: Some of the product images in the 1932 catalog were obviously produced much earlier, since they show features that were already outdated by the time the catalog was printed – most obvious in the pickguard type which underwent several changes in the 1931–32 period (see also Close-up #38). Examples: The Bretton Tenor + Strand mandolin are models we have no documentation of any first-year examples yet – however we assume these models were offered in 1931 since depicted in the catalog with an early "Type 1" pickguard.

Distinctive features of 1931 Masterbilt models

When looking at surviving examples of 1931 Masterbilt models we notice that many of them show signs of later modifications – some obvious, some less so. But there is a number of instruments in still pretty original, unmodified condition – historically important examples providing evidence for our research. Our findings in a nutshell:

Broadway 5319 bracing  Triumph 55788 tonebars

Right: Later Triumph model, carved top with two parallel tonebars

Hollywood Tenor 5104
1931 Hollywood Tenor SN 5104 – small 13⅝" body, flat(?) top. By 1932 the model was upgraded to a 15½" wide, carved archtop. Note the 1931 pickguard "Type 1", without screws through the plate. By 1932 the headstock of the Hollywood received fancier pearl banners.  (Photo by Archtop.com)
