The Refined Resonator: Reviewing National’s M1 Tricone

“The Mississippi Delta Was Shining Like a National Guitar” – Paul Simon, Graceland

Introduction and Background

When I first picked up a guitar, I wanted to be a flat-picking bluegrass player. Sometime thereafter, I concluded that I did not possess the speed or accuracy to play that style, and adopted fingerstyle guitar with Travis picking as my basic playing approach. It was the best decision I ever made regarding the instrument. When I took a quantum leap in focus and interest in guitar playing my pathway to achievement was to learn Acoustic Country Blues, which happens to be huge body of music with many different sub-styles to choose from. The structure of Country Blues was appealing to me because it speaks to my sensibilities as a musician, is distinctly American and it serves as the foundation for a large swath of the music I grew up with in the 1960’s and ’70s.

Fender Resonator…

After one of my ongoing lessons at my local guitar shop some years back, I walked by a Fender resonator guitar hanging on the wall and it occurred to me that a resonator might broaden my Country Blues sound palette. I responded instantly to the distinct sound that a resonator cone makes when the guitar string is plucked and merrily played a couple of Mississippi John Hurt tunes that I’d been working on. The Fender string action was supple and easy to play, sounded good too, but it felt insubstantial in construction. I decided at that moment that I would pursue the acquisition of a resonator, but guitar snob that I am, I wanted to acquire a fine instrument. Of course, what’s “fine” is open to debate and a matter of taste, but with my limited knowledge at the time I referred to Paul Simon’s lyric from “Graceland” and decided to chase after a National guitar.

Catfish Keith and a National Tricone

I found myself on Iowa’s legendary bluesman Catfish Keith’s website whilst doing research on resonators. At that moment, I was a bit overwhelmed by the numerous models and resonator types to select from. In correspondence, Catfish was kind enough to write me a brief dissertation about Nationals and recommended that I consider a single cone guitar for starters. In short, resonators are typically manufactured with a single large, spun aluminum cone, or three similar but smaller cones, referred to as tricones.

Catfish and Penny wintering in Mexico in happier times before the pandemic…

As a side-note, both Catfish and his wife Penny are incredibly gracious and generous people and I had the great, good fortune of taking a private lesson with him at his home in small town Iowa. He taught me the nuances of playing his arrangement of “Police and a Sergeant,” a variation of an old Robert Wilkins tune.

Catfish is a representative/distributor for National guitars and sells them new from his website. At that moment I was ready to take up Catfish’s advice by acquiring a single cone resonator, but I decided to go on the used market to save some money. I’ve written before about the savings that can be made by purchasing used guitars online from Reverb… there’s quite a drop in value when you drive a new guitar off the lot. I’ve subsequently revised my opinion on buying used versus new, as I’ve experienced set-up issues, cracked bodies, sketchy electronics and twisted necks when buying used. In fact, all 6 of my current and varying style guitars were purchased new, because I’ve traded off my pre-owned ones.

National NRP B Single Cone Resonator

Nevertheless, my first National resonator, was a mint conditioned and bargain priced NRP B steel, single coned guitar. I was delighted when the NRP arrived but was astonished at how difficult it was to play, compared to the Fender resonator that I tested in my local guitar store. I subsequently realized that the action was set-up pretty high for slide playing, rather than finger picking, which was not clearly elaborated on the Reverb website. This high action play was initially viewed by myself as a disaster of biblical proportions, but then I decided to make lemonade from lemons and go down the bottle-neck slide rabbit hole and never looked back!

National Resorocket WB

Metal resonators have their own distinct sound and vary somewhat depending upon the type of metal from which they are constructed. My NRP was steel so it had a bold and present sound. To my ear, you could even say it was a bit harsh sounding, which is actually appealing to a lot of blues players. Overtime, I wondered if a wood bodied resonator might be more appealing to my sensibilities and returned to the marketplace for a used wooden body resonator. I subsequently, through Reverb again, found a sweet deal on a wood bodied National Reso Rocket (WB model), which I subsequently equipped with a Hotplate electronic pick-up system so I could run it through an amp. When the WB arrived, I quickly discerned that the guitar was also set up with high action to facilitate slide playing. Even though I would have preferred to have had a resonator that I could easily fingerpick, I was loathe to have my local shop grind away at the nut or biscuit bridge to lower the play, so I resigned to playing slide on both resonators. You’d think by then that I would have learned not to buy resonators, used online…

At a workshop with Mike Dowling… I am holding my WB

I played my wooden body in Open D and the steel body in Open G for a couple of years or so, and then it occurred to me that I was not playing the steel body near as much as the WB, mostly because it was super heavy and I found it unappealing to my ears. It was time to put the steel NRP on the trading block, which I did and the complete story of my acquisition of a National Resolectric can be found here. In my review I don’t think that I mentioned that while testing out the Resolectric I was also interested in auditioning an M1 Tricone; however, the one that had been in the store had sold the day before my arrival. I had seen and heard an M1 Tricone when I attended a guitar workshop taught by Mike Dowling in Minnesota a couple of years earlier. I thought it was an interesting guitar and never forgot about it.

Me and the WB…

I played a lot of hours with the WB on my lap, but became increasingly frustrated that I could not play the guitar fingerstyle, which was always my original intent when I set out to own a resonator. At Mike Dowling’s suggestion, I investigated the use of the new National Revolution aluminum biscuit to adjust the WB’s play, which I installed but eventually removed. I wrote about that experience here and here. At some point thereafter, the notion of trading the WB for an M1 that would be initially set-up for fingerstyle arose from my subconscious. In fact, I asked Dave’s Guitarshop for a trade quote on the WB when I saw an M1 for sale at the store, I got a very nice trade deal, but the M1 sold before I could arrange an appointment to visit the store. The National M1’s don’t collect dust at Dave’s Guitars, but move very fast out the door. That was February 2021. My contact at the store told me that they had another one on order and that I should check the store’s website for its arrival, which I did almost everyday since February. I also kept the correspondence that documented the trade-in value of my WB.

I Purchase a National M1 Tricone

When I was considering the acquisition of an M1, I did my due diligence and researched the Youtube universe for reviews and tone examples. One of the best videos I found was a direct comparison between three of National’s wooden bodied resonators: The El Trovador, a deep bodied single cone guitar, an M1 Tricone, and finally a Resorocket WB, like I owned. This really excellent comparison was produced by Organic Sounds:

In the video, the El Travador is bold, rich sounding, loud and offers clean highs with great bottom end low frequency tonality, with the mid-range tones taking a back seat. It’s little wonder that recording artist Mike Dowling favors the El Trovador among all the wooden bodied Nationals. I like the El Trovador, but the deep body would be sure to cause me shoulder pain. On the other extreme is the Resorocket, which by comparison, sounds most metallic, more twangy and perhaps even a little pointed/shrill sounding. Furthermore, the Resorocket, which I am intimately familiar with, has some sort of frequently occurring overtone that sounds like a cat yowling. That overtone I do not like and experienced far too often when I played mine. Finally, the M1 sounds refined, sweet, balanced, very clean and musical, with individual notes clearly differentiating from each other. The tonality is also nice and even from high to low end frequencies with the mid ranges well represented.

Tricone resonator
Single Cone Resonator

It is not surprising that the John Dopyera, who created National Guitars with the introduction of tricone technology was reluctant to start producing less expensive, larger single cone variants at the urging of his partner George Beauchamp. He revered the “fine instrument” sound of the tricone. In fact, Dopyera quit National and founded Dobro with his brothers in part because of the tricone vs single cone controversy. Still today, the three smaller cones of the Tricone design are considered by many listeners to be more refined and balanced sounding and I tend to agree with that assessment. While the terms “refined and balanced” are positive sounding terms, the more forward, in your face, perhaps brash sound of the single coned resonators are favored by many, particularly blues musicians.

Here again we can see a different take on the M1 versus the El Trovador as played by Mike Dowling. Dowling has a long connection with National, and I believe he prevailed up them to reintroduce the El Trovador into their product line. Dowling is arguably one of the finest resonator players walking the earth:

By Dowling’s description, the El Trovador is “more pointed” and “dryer” sounding than the M1, while the tricone offers more complex coloration. The differences between the two instruments are a function of cone size, cone number and chamber size caused by the 4 versus 3 inch body width. As I watch Dowling’s body language and commentary closely, I think he prefers his beloved El Trovador, but I like the M1 and decided to chase one down if I could.

For me, the easiest place to acquire an M1 would be Dave’s Guitar shop in LaCrosse, WI. It’s 2.5 hours away from my home by car and they make trade-ins absolutely painless. The challenge is to move quickly when Dave’s gets an M1 in stock because they move out very rapidly. So, for four months, I would routinely check Dave’s website for M1 availability.

Dave’s vintage guitar collection

Then, Friday night a couple of weeks ago as my wife was calling me for dinner, I did a quick check at Dave’s, which I had not done for a day or so and, low and behold, they had a new delivery of an M1 showing on their website. Knowing the M1’s don’t last long, I grabbed it and paid for it immediately and planned to head over to LaCrosse the next Saturday morning! I invited my wife to come along and we made a fun day of it. It was a beautiful day for a drive and we stopped in the nice Iowa town of Decorah to eat lunch at a bagel bakery, whose owner we knew.

After lunch we headed over to Dave’s in LaCrosse. During these late pandemic days you still need to visit by appointment. I called early that Saturday morning and Dave himself answered and set things up for our visit.

When we arrived, Annette and I were ushered in. I dropped off my Reso-Rocket WB and it was accepted with no fuss whatsoever. Before I could say Jumpin’ Jack Flash they had a new price tag on the WB and by Monday it was advertised online. I think it sold by Wednesday. Wooden bodied Nationals move quickly and that’s why I was given an excellent trade-in value and they subtracted it from the online price that I paid out the night before. No muss, no fuss and that’s why in my experience Dave’s is one of the smoothest operations in the U.S.

Me and my new M1 getting acquainted at Dave’s

The new M1 was sitting by the front desk waiting for me. I popped open the case, pulled it out and looked it over. It was a stunning piece of industrial artwork. As a new guitar should be, it was immaculate. One of the standout features of the M1 is the lack of the silver/chrome hubcap like cover over the resonator cones. Instead there is a metal cover that is painted the color of the mahogany wood that comprises the body. It is a unique appearing resonator unlike any other in the National product line.

I sauntered over to a quiet corner of the store to try the M1 out. I wanted to make sure there were no problems before I walked out of the store. I threw my iPad, which contains my tune charts on an amp, grabbed a stool and tried to play, but the guitar was woefully out of tune because the new factory strings on it had never been stretched, so it took me a few minutes to get the tuning stabilized. I played through a few charts in standard tuning with fingerstyle technique (I never use a plectrum ever) and realized quickly that the set-up was to factory specs, meaning that both slide and fingerstyle play were easily and effectively possible! One of the store techs who visited me to discuss installation of a pickup confirmed my conclusion about the guitar’s set-up.

I find a 1950 Fender Broadcaster!

I stretched the strings again and then re-tuned the guitar to Open D and pulled out my National solid brass Tonedome slide and played a couple of bottleneck tunes too. There was a young fellow wailing away across the store on a Stratocaster which made listening to the M1 a bit challenging; however, sometimes good enough is good enough and I concluded the axe was definitely a keeper.

Me in front of Dave’s Guitars iconic street signage

Annette and I concluded our visit by visiting Dave’s famous and extensive vintage guitar collection where I was delighted to identify Leo Fender’s first electric guitar model, the Broadcaster, a truly historic instrument. Next to it was a “Nocaster” and finally the first Telecaster, which was the Broadcaster renamed because of a trade name dispute with the Gretsch Company.

On the way out, we stopped so Annette could photograph me in front of Dave’s Guitars iconic street sign. As you can see I posed with my new axe. Afterwards, I stowed the guitar in the rear of my hatchback and headed home across the Mississippi River back to Iowa. A good day indeed was had by all…

I Review My New National M1 Tricone Guitar

To the right you can see the National Reso-Phonic M1 that I purchased from Dave’s Guitars and brought home to Iowa. It’s a slot-headed, 12 Fret, bound mahogany neck, ebony fretboard, layered mahogany body, tricone resonator, with grained ivoroid binding. The appearance is unique as compared to other National Reso-Phonic guitars in that it is wooden constructed, but most conspicuously lacks the “hub cap” type cover that is typical with single cone resonators. The fact that the metallic tricone cover is the same color as the body gives the belly of the guitar a more uniform appearance. The design of the sound porous screens that protect the resonator cones, combined with the slanted grid openings in the upper bout of the sound board give the guitar a distinct art deco sensibility. It is a stunningly singular appearing acoustic guitar.

M1 Tricone Slotted Headstock

Let’s consider the M1 from the top at the headstock and follow the string line down to the tail piece. Again, you’ll note that the guitar is equipped with a traditional appearing slotted headstock. Unlike the Reso Rocket WB that I traded for the M1, the headstock does not have a pearloid veneer, but is instead stained wood embellished with a traditional product logo decal. This is similar to the Martin guitar approach where for many of their beloved models they stick a decal on the headstock. For the cost of this M1, an inlaid logo would have been a nice and expected adornment. On the other hand, I like the overall look of the guitar, so I’ll stop complaining.

The tuning machines, with exposed gear works, are clustered in groups of three and equipped with attractive ivoroid knobs. All tuner actions are smooth and precise, unlike my old Reso Rocket which had a very stiff and difficult to use D-string (standard tuning) tuner. Finally, you’ll note that the outer strings on the fretboard (E & e) are strung into their respective tuners from the outside to the inside of the headstock, while the remaining strings (A, D, G & B) go from the inside to the outside. This stringing technique which can elude guitar store guys, prevents the outer strings from chafing the headstock wood. Finally, the strings enter the fretboard by passing over a bone nut.

M1 Fretboard

To the right you can see the M1’s fretboard, an ebony strip of wood bound to the mahogany neck. The ebony is black with blond striations, which is the sustainable fashion begun by Bob Taylor several years ago when he bucked tradition and refused to toss aside ebony wood that was not perfectly black. I like the blond hints on today’s ebony fretboards. The comfortably wide neck is bound with grained ivoroid. Finally, the guitar was strung with John Pearse 13’s spec’d for resonator guitars.

The neck attaches to the guitar at the 12th fret. This particular model has no cutaway, which is one of the features I miss when comparing the M1 to the Reso Rocket WB. When playing bottleneck it’s nice not to have to be crowded by the body at the 12th and 13th frets.

The M1’s upper bout

To the left you can see the M1’s upper bout, with its rounded shoulders, the art deco sound port grills, and the inlaid Mother of Pearl dots that adorn the fretboard. The soundboard, like the guitar’s sides and back are manufactured from layered mahogany. There are some very rare exceptions when National makes a guitar body from solid wood, with the preponderance being layered. The layered body and its shape serve the role of imparting a woody tonality that colors the sound produced primarily by the three small resonator cones.

The top’s mahogany veneer does a great job of revealing the wood’s grain and reflecting the rich reddish brown stain that gives the wooden Nationals their distinctive appearance.

The M1’s lower bout

The M1’s lower bout is where the rubber meets the road. You can see on the right where the triangular-shaped metallic cover sits above the three resonator cones. The metallic cover is cut with art deco shaped openings that allow the resonator tones to escape. A silvered metallic grill protects the cones.

The guitar strings each rest in a groove cut into a wooden saddle that is glued to an aluminum t-shaped bridge, the ends of which each contact a resonator cone. The t-bridge transmits the vibration of the strings to the cones. The metallic cover has a raised t-shaped shield to protect the saddle and bridge. The strings then exit the saddle/bridge area and are bound down to a standard National tailpiece which is held in place by a combo screw/strap button located in the bottom of the guitar.

Examining the t-bridge indicates that the heavier strings are biased towards two of the cones, whereas the lighter strings are handled primarily by one cone, although all the strings in some way affect all three cones. This relationship of string locations, t-bridge and distribution of vibration to the resonator cones is what gives the M1 its balanced and sweet tonality.

Above left you can see the neck join to the body. The neck is held in place by a “stick” that runs the length of the body’s interior. As with most modern, premium guitars the neck is equipped with a truss rod to adjust play variations that might result as response to humidity in the ambient environment. Also visible are the grained ivoroid bindings on the body. The M1 is a neat, precision constructed, manufactured product that benefits from competent highly trained builders along with the use of numerical, computer controlled machine tools.

You will note the absence of a guitar strap button at the base of the neck. I intend to have one placed by my local guitar shop; however, I plan to order a Waverly white ivoroid button and felt washer from Stewmac, because my guitar shop offers only prosaic silver and/or black metal buttons, or high end Schaller strap lock buttons, which I don’t want to use with this guitar.

Also, above right you can see a shot of the M1’s back. The stained veneer of the layered wood back shows off the beautiful straight grain of the mahogany from which it is constructed.

Finally, as with all premium guitars, the instrument is supplied with a custom-made hardshell case. The guitar fits in snuggly and the outer side of the upper lid has the National logo embroidered into it, which is quite stunning. A word of caution about the logo though… it is easy to muss up if it comes into frictional contact with another object like an adjacent guitar case while traveling in the back area of a car.

To close out this review, I am sharing some sound bite examples of the M1. These were recorded with amplification through a Fishman Loudbox Artist with a Shure SM-58 mic. The actual recording was done with an iPhone 11 equipped with a Shure MV-88 and processed through Apple iMovie.

I would prefer to have a pickup on the guitar but that’s been more challenging than I anticipated. The go-to pickup on resonators, in my judgement, is made by Highlander. I had one put into my steel NRP and it worked well, though you had to haul around a battery powered preamp. Sadly, it appears that Highlander is no longer in business. Further, I was not sure I wanted a guitar tech drilling holes in the M1. Now it seems that the go-to pickup are those made by Jason Krivo Flores out in Portland, OR… I have one on order. The tone samples online sound great; however, the pickup is a bit idiosyncratic in that it attaches to the guitar with blue tack. I will probably write a blog entry about the Krivo after I’ve worked with it for a while.

Anyway… below are two bottleneck tunes recorded in Open D followed by a fingerstyle piece in standard tuning…




In conclusion, I feel fortunate to own a National M1 Tricone. The wait time on a new M1 is currently 6 to 8 months and I’m not getting any younger. The instrument itself is a beautiful example of industrial art and with its balanced tonality plays well, as currently set up in either bottleneck or fingerstyle mode. Highly recommended.
