Personally, I feel theTricone's smoother, more complex tone is the bestNational sound and look! A roundneck tricone (in my opinion) is theNational resonator instruments use very thin aluminum speaker cones,Known as "cones", to mechanically amplify the sound of theInstrument. This is attributed to their brass, not steel,Body material. Many blues players feel the combination of singleCone resonator, steel body, and mahogany neck used on theThe fancier nickel plated brass, single cone metalbody instruments such asThe Style O don't have as bluesy a tone asThe less ornate Duolian. The vibration fromThe strings goes through the saddle, which in turn vibratesThe T-bridge, and then the three cones. Two ofThe cones are on the bass side, and one on the treble side.Rather than a wooden biscuit bridge, there is an aluminum "T"Shaped bridge that connects to the center of each of the cones.A maple wooden saddle sits atop the T-bridge. BecauseThere is fairly direct transmission of vibration from the stringsTo the resonator, the single resonator guitar is the loudest ofIn a tricone, the three 6" cones are set in a triangle. The biscuit has aWooden maple saddle which the strings pass over, like aBut unlike flattop acoustic guitars where theVibration of the wooden body creates the sound, in aNational resonator instrument the body acts as a speaker cabinet.When the strings are played, the vibration goes through theSaddle to the bridge and then vibrates the speaker coneCausing it to "resonate" and amplify the sound. Some National models have a single cone,Others have three smaller cones (known as "tricones" or "triplates").In the single resonator models the convex 9.5" diameterCone has a maple "biscuit" on top of the cone. Squareneck models can not be played like aStandard guitar. This refers to the shape of theBack of the neck. Be aware that almost all Tricone models came withEither a "squareneck" or a "roundneck" (and the necks are notInterchangable). Beyond that,All the Tricone models are collectable, with theFancier styles 2,3 and 4 (all engraved) being more collectible than thePlain style 1 Tricone. So the most collectible Nationals will alwaysAnother consideration with Nationals is the number of frets clear of theBody. AndSquare neck Nationals also have little collectibility compared toRound neck models. But note Country-style players all seem to preferHence wood body National resonator models have limitiedAppeal and are not nearly as valuable as a metal body Nationals. TwelveFret instruments are a little louder since the body is bigger. In late 1934, National shortened the body ofTheir single cone instruments to give 14 frets clear of the body(note all Tricones stayed at 12 frets clear and were never upgraded).The early to mid-1930's made this switch in design.Left: Straight cut "f" holes on a 1929 Triolian.Right: Rolled "f" holes on a 1934 Sytle O.Resonator Single Cone Sound Differences: 12 versus 14 Frets.The sound of 12 fret and 14 fret National single cones is different. Prior to late 1934, all Nationals had12 frets clear of the body. But on the other hand, 14 fret instruments are morePlayable. Hence 14 fret instruments sound and lookMore "compact". This made the body even stiffer, butAlso decreased the size of the body. The stiffer body forces the vibrations to theResonator instead of being absorbed by the body, hence giving better tone.When National switched to a 14 fret neck, all they did was toShorten the body, making it smaller. Prior to 1933, National straight-cutThe F-holes in the single cone metal bodies.Starting in 1933, National rolled the edges of the F-holesMaking the body stiffer. Photoshop for mac with touch barNote the neckIs a "sandwhich" first the fingerboard, than a middleStiffening layer (about the same thickness as the fingerboard),And then the bulk of the neck. Prior to this, most 12 fret necks have a completelyFlat fingerboard radius (except for some 1934 twelve fret models).This is very uncomfortable to me (though if youPlay bottleneck this makes little difference).A 14 fret, slotted peghead National neck. Also, whenNational switched to 14 fret necks they changed to a 10 inch fingerboardRadius. The pre-1933 single cone models seem very crude to me. I also like the 1933 to late 1934 twelve fret, rolledF-hole models too, but then do seem less playable because of the 12 fretNeck. For the most part, theseGuitars are inexpensive, low-end models. Introduced in late 1961 (but not availableUntil 1962) and were made only to 1965.
