Shutt’s Harp Guitar Prototype?
by Gregg Miner, November, 2014


Before you get too excited, no, this is not the amazing Shutt Mando-Bass-Harp-Guitar.   That patented and catalogued instrument has yet to be found – and it may be that only one was ever built.  Equally rare – again, with only one example known from this 1912 Crescendo photo, and never found – is Shutt’s standard Sub-Bass Guitar. 

This wonderful discovery is neither of those.  It was built by Frank J. Oppitz, a man who worked for Shutt during the very brief period of his short-lived mandolin and guitar manufacturing business.  Remaining in Oppitz’ family until present day, there is, regrettably, no solid information on it.  The fascinating instrument was brought to light recently by his granddaughter Jeanette Surratt.  The family has long surmised that it was Grandfather Frank’s “personal instrument.”  I suspect that it was built in the Shutt shop (a small “factory” on the second floor of his Topeka, Kansas home).  It has no label or markings, and indeed, Frank appears to have played it quite a bit (while taking very good care of it).  But did he build it as an “employee instrument” for his own amusement?  Or was it something more?  

Taking everything into account, I find it at least equally likely that this could have been built as a first experiment or prototype for a Shutt harp guitar.

For those unfamiliar with Shutt, you might pause here to read my full article on this obscure but important American maker.  Or at least my short new blog essay on this enigmatic maker.  In a nutshell, Albert Shutt was a small town music personality who seems to have been inspired by Gibson’s instruments into competing with them.  Clearly influenced by their instruments, he came up with many of his own variations and “improvements” on many of Gibson’s popular features.   For example, according to Roger Siminoff, it was Shutt who first introduced the elevated fingerboard extension, later used on Gibson mandolins and guitars.  Shutt also created the first archtop mandolin and guitar with F-holes and patented his own elevated pickguard and compensating bridge.  He may have even installed truss rods long before Gibson patented theirs.  Of particular interest to harp guitar historians is Shutt’s ultimate achievement (even if it may have been something of a “white elephant”):
The Mando-Bass-Harp-Guitar, which was intended to be a perfect combination of Gibson’s popular harp guitar and brand new mandobass!

Shutt's c.1912 Mando-Bass-Harp-Guitar with truss rod covers?


Jeanette has little information on her now-historically-important grandfather, noting that “My grandfather was a master carpenter who enjoyed music as his hobby.”  That he made violins is known, but whether that was his specific trade is not known.  He played guitar as an amateur, and perhaps studied with Albert Shutt himself, whose main occupation was teaching banjo, mandolin and guitar.

A love of music was passed down through the Oppitz family.  A piano player and occasional songwriter herself, Jeanette says of Frank’s son Frank Jr.: “My father was a musician that could do anything with wood as his hobby.  He played the trumpet and for years was highly involved with the Arab Shrine band in Topeka, Kansas.” 

Newspaper searches have revealed that Frank Oppitz Sr. played the guitar in Shutt’s mandolin orchestra groups.   The first of these appearances occurred in 1911 and featured a “Guitar duo” by “Messrs. Shutt and Oppitz.”  Ten years later, another appearance of Oppitz playing guitar in Shutt’s “Stringolio” club occurred in July, 1921.  While the instrument manufacturing enterprise had almost certainly been abandoned by this time, the men undoubtedly kept in contact through their musical activities.  It’s easy to imagine the two playing harp guitars for these concerts!

Note Oppitz as the first witness

And again 3 years later

We know they played music together from at least 1911 to 1921; when did they work together?

Frank's granddaughter recently discovered that "he was a master carpenter for the Santa Fe Railroad.  (My) Dad said that when they would strike, he would work full time for Albert until they were called back to work.  How often that happened, I can't tell you."

A couple of clues can also be found on Shutt’s patents.  Frank J. Oppitz is one of the witnesses on Shutt’s design patent #D41792 titled “Body for Stringed Musical Instruments” (depicting his mandolin with newly-refined scrolls).  This was filed on May 22, 1911 and granted the same year on September 19th.  Curiously, Oppitz didn’t witness the very next patent, which was for the mando-bass-harp-guitar (“Double Bass Guitar”).  Nor did he appear on the following elevated pick guard patent also filed in 1912.  Then his name again appears on design patent D45969 – the plainer, asymmetrical mandolin design – filed in March, 1914.  The late date of this patent is a conundrum I discuss on the Dating page.  I also find it interesting that this body shape (slightly different in the patent drawing) is the one he used for his harp guitar.  Specifics or conjecture aside, we know that Oppitz was definitely present during the peak of Shutt’s mandolin and guitar building activities.

The output of Shutt’s mini-factory is unknown, but only a dozen or so Shutt instruments are known to survive.  Despite the extensive and detailed catalog along with Shutt’s several advertisements, his distinctive instruments do not seem to have found a market, and all indications are that they were produced for only a few very short years and probably through individual orders only. 

It’s not known whether Albert Shutt specifically built any of his instruments himself; his grandson Jack mentioned having help – “especially carving tops and backs – from violinmakers.”  Though we have no hard evidence of this, we do now have some knowledge and evidence of at least one of these builders – Frank Oppitz.  He even left us an example of what is allegedly his personal work.


I was thrilled to acquire this personal/prototype harp guitar from the family in 2014.  It was in remarkable condition for a one hundred year old instrument: only one significant open top crack and worn frets with binding issues due to the fingerboard shrinking.  After restoration by my museum quality expert, it looks great (I’ve been advised not to attempt to polish or otherwise restore the black top finish).  Let’s take a look:

I believe that this may be the earliest archtop guitar with F-holes, something Shutt beat Gibson to by over a decade.  The top and back are very finely carved, with a less pronounced arch than Gibson’s.  The bracing and support posts are interesting to compare as one has a center soundhole while the other has opposing f-holes.  The Oppitz/Shutt has a small longitudinal brace just inside the bass side f-hole.  Compare this to the Gibson bracing (2 bars and a horizontal brace below the soundhole (patent drawing below).  Gibson added two thick wooden support posts inside on opposite sides of the soundhole (Nov, 1908).  Similarly, Oppitz installed one post in the center between the F holes.  These photos show it terminating at the neck/shoulder block and tail block.

Shutt/Oppitz also appear to have purchased the Gibson sub-bass friction tuners – either from Gibson or their supplier.  Standard friction tuners are used on the neck, like the earliest Gibsons.

Oppitz' case even contained the exact same Gibson catalog "Sub-bass Tuning Key"!

Here is an interesting feature, occurring also on at least one Shutt scroll mandolin.  This portion of the body’s upper perimeter – from point to point – are not “sides” but a chunk of wood (maple, most likely) created from three laminated " pieces.  Totalling 2-1/2" in width, it’s about an inch in depth, spanning this whole top perimeter, with the sides attached to it and covering the ends up to the corners.  Something similar was seen in my giant Bohmann harp guitar, though that extended neck-shoulder block was entirely covered by the sides.

And it seems that the Gibson harp guitar may have its own complex version of a "super neck block" like the Bohmann, fully covered by the sides.  Again, Shutt and Oppitz had likely taken apart a Gibson or two...

If this was a shop worker’s “personal instrument” and not a specific Shutt prototype, then it appears nevertheless to have been built like all of the Shutt shop’s output, with the same techniques and materials and plausibly at the same time.

Note for example that it appears to have been built with the c.1912 “Style B” guitar mold (far right), but with the right upper shoulder moved out to accommodate the neck moving to the right (this is part of the top slab and not part of any side mold).

The dimensions I believe are also roughly the same.

Other similar touches include:

The classic Shutt guitar tailpiece design, as seen in the catalogs and extant specimens.

This consists of a thin nickel tailpiece, not unlike Gibson’s, with a screwed-on cover piece of black-painted maple.

A layer of felt presumably serves as a “buzz barrier.”

In the two known Shutt harp guitars, the Mando-Bass-Harp-Guitar (left) has a similar two-piece set-up; the Sub-bass Guitar (right) has a single wide one. 

The shape of Oppitz’ guitar head is rather similar to the “Artist’s Model” scroll mandolin head.  He veneered his with celluloid and bound it with ivoroid.  Notice how he bends this along with the multi-ply headstock into his required tight S-shape.

Like the Gibson harp guitar, Oppitz added a support rod, either from the onset or added later.  Interesting that the wood shim looks newer to me.

The fingerboard had shrunk in width causing the binding to “scallop.”  Below: All original binding re-attached after fret dressing.

The back and sides appear to be a plain maple, stained to look like mahogany. 

Binding before...

...and after


Assuming that I’ve demonstrated that Oppitz built this harp guitar in the general 1911-1915 period of Shutt’s production, the next question is how it falls in line with the dating specifics of the Shutt catalog instruments and patents.  That has proven to be a puzzle, as the catalog contains apparent inconsistencies.

On the new Shutt Dating page, I’ve created a chart to try to wrap my head around it.   My detailed analysis and reasoning are there; you may wish to corroborate or suggest alternatives.  It ends with a simple bullet re-cap, which I’ll repeat here, with an extra bullet concerning the Oppitz harp guitar.

My conclusions:

  • The first Shutt mandolins were built around the time of the December, 1909 patent filing for the first design.

  • From early 1911 to early 1913, Shutt created his full line of instruments: all models in both body shapes. The scroll models came first, then the simpler models.· 

  • His first and only catalog was then printed in the first few months of 1913.

  • Both production harp guitars appeared in this catalog, while the sub-bass guitar additionally appeared in The Crescendo September, 1912 issue.

  • Thus, if it was a first “prototype” harp guitar, the Oppitz instrument preceded these sometime in 1911 or early 1912. If it was simply a “one off” personal instrument, it was still probably built around this same time.


Here is where the proud new owner would typically boast how great the instrument sounds (honestly, they can’t all sound fabulous, can they?).  Well, in my collection of pretty fabulous-sounding harp guitars, this is unfortunately not one I can boast about. 

The thick-topped Gibson harp guitars are infamous for their surprisingly thin and dry, clunky sound.  The Oppitz guitar – in virtually as-built condition – sounds inexplicably and dramatically worse in comparison.  Somewhere between an old Sears guitar and a plastic Maccaferri.  In fact, a gypsy-jazz rhythm “le pompe” is perhaps the one thing this instrument would work well for.

I can’t quite understand why.  I’d always heard good things about Shutt mandolins; David Grisman compares both the quality and tone favorably to pre-Loar Gibsons, as do collectors Lowell Levinger and Jim Reynolds.  And Frank Oppitz theoretically had a hand in those instruments as well.

Construction?  Design?  I believe that this was one of the very first F-hole archtop guitars ever made – ten years before Lloyd Loar’s for Gibson (and of course Gibson harp guitars never switched over to F-holes).  Like Orville Gibson, Albert Shutt based his instruments on violin principles.

Just as Gibson Style U’s were recommended to be gut-strung, perhaps that would help here?  The strings on it as received were all steel/nickel – the classic Black Diamond brand, while the subs of unknown make were also full steel, ranging from 0.040” to 0.070”.  In the case were old silk and steel neck strings, and I suspect the entire instrument was originally fitted with S&S.

Speaking of the case: The “surprise in the Cracker Jack box” for every vintage instrument collector is that moment when they first open the accessories compartment in the musty old case.  This was a particularly fun one!  

Used and un-used vintage strings, an early capo, some extra friction tuners, and these bizarre metal fingerpicks.  I’d seen an ad for these in a 1920’s Cadenza – they’re meant to grip the finger more safely I suppose.  The original catalog is just the second known, and was a bonus from the owner.

Regardless of the disappointing tone, this remains a rare prize in the Miner Museum.  

My sincere thanks to Jeanette and the family for entrusting this historical treasure to my care.
