Riversong Glennwood TS6 Review

The first and perhaps most important thing to know about Riversong’s Glennwood TS6 is that it aspires to hybridize elements of electric and acoustic guitars. This is not a new idea—certainly not in the amplified acoustic era, where the straightest route to eliminating feedback is by reducing the resonant elements that cause feedback in the first place. Some acoustic/electrics achieve these ends by slimming bodies down to electric-guitar thickness. Riversong, however, sticks to traditional acoustic formula by making the TS6 a full-sized instrument. Its dimensions are a little bit atypical: the 16″ wide body and 4 3/4″ thickness are about the same size as Martin’s “jumbo” J body and the Taylor Grand Pacific. The pretty silhouette also echoes the curvaceousness of those larger guitars. Those similarities sometimes feel like an exception, though. At nearly every other turn, the TS6 very happily breaks the acoustic design mold.


 A Nuts-and-Bolts Approach

You don’t have to look very hard or be an acoustic guitar construction expert to see that there is a strong deconstructive thread in the Riversong’s design. The gap in the top behind the bridge, the slim heel, and, above all, the bracing and neck-through build are major breaks from classic acoustic design philosophy. These very overt differences are also a clue to how the Riversong stretches the definition of what an acoustic guitar is.

Most tradition-minded acoustic builders would consider the small space aft of the bridge detrimental to a resonant top. And few would opt for the bolt-on neck and through-body re-enforcement that runs the length of the body. These obvious deviations from acoustic design dogma are just the start. Peek through the side port and you’ll see “skeletized” bracing that looks like sections of a cantilever bridge in miniature. Adjustment to the action and neck tilt? They’re made with an Allen key that you place through an access cavity on the back of the guitar at the heel.

All these very unconventional elements are executed at a very high level of workmanship. I failed to find a construction miscue anywhere. The fretwork is pretty much perfect and the solid wild cherry back and sides, Sitka spruce top, maple neck, and walnut fretboard are all shaped and put together with obvious care.

Electrified Vibrations

Considering that the TS6’s primary mission is that of a hybrid electric/acoustic—and that so many of its fundamental design elements would traditionally be considered detriments to acoustic tone—the TS6 sounds pretty good unplugged. If I had to guess, I’d venture that the Jumbo-like dimensions were adopted, in part, to offset the diminished volume and overtones that could result from the neck-through design. Yet the TS6 is notably resonant, particularly in the low-midrange, and exhibits nice sustain. It may not be as loud or detailed as a dedicated acoustic of similar dimensions, but it holds its own, and the combination of projection from the side port and soundhole creates a nice composite sound image that would be well worth miking and doubling with the pickup signal in a studio or on a quiet stage.

The TS6’s amplified qualities and its electric-like playability are the main attraction, though. The Fishman Flex undersaddle pickup and preamp hold up pretty well to hard strumming without getting quacky, but the guitar and pickup work best together in dynamic fingerstyle settings. I tended to work from fairly tame tone settings on both the TS6 and the Fishman Loudbox I used for amplification, but the TS6 left ample headroom for adding sparkle to the basically well-rounded tonal foundation. Playability, as advertised, is excellent for a flattop. The 16″ fretboard radius and jumbo frets make it easy to fret with a light touch. The 1 5/8″ nut width and the neck profile (which to me felt at various times like a 1960s Guild or a Rickenbacker) also conspire to lend a very electric-feeling experience. The neck-thru system’s ability to facilitate and withstand pitch-bending neck wobbles also checks out just as Riversong claims. I can’t remember using an acoustic in this fashion so readily, dramatically, and with such negligible effect on tuning stability.

The Verdict

At around $2,000, the TS6 is a flattop for players committed to the unconventional or performers that can also afford to keep a classic flattop around for recording pure acoustic tones (if they are concerned with such expressions). It’s a niche instrument, but it does a brilliant job of blurring the lines between acoustic and electric.

Martin 000-18 Modern Deluxe Review

martin 000 18 modern deluxe review

It would be easy for a company of Martin’s stature to coast every now and again. Maintaining brand mystique is exhausting in an age when hype rules the day. Keeping quality and substance intact—and maintaining commitment from the folks on the shop floor that deliver it—is even harder. But year in and year out, Martin continues to make instruments that simultaneously dwell in the realms of the practical, the musical, and the exquisite.


At nearly $3,600—a full $1K more than a standard 000-18—it’s a good thing the Martin 000-18 Modern Deluxe looks and feels as luxurious as it does. But while details like a pearl-inlay, 1930s-style script logo, EVO gold frets, and flawless lutherie and woodwork at every turn will make even the most cynical function-before-form grump pause, it’s the functional facets of the 000-18 Modern Deluxe that impress the most.

Building on Perfection

The 000 body (which shares dimensions, more or less, with the OM) is a cornerstone of the Martin line. Mating it to the “18” tonewood formula, which combines mahogany back and sides, adds up to a guitar that, to many ears, is the essence of balance and sweetness. So how does one refine something that’s so near perfect to begin with? Well, even in the case of an architectural masterpiece there’s always room for a little tasteful landscaping, and Martin has done a fair bit of that here. The 1930s-style logo is inlaid in pearl, while the body binding is East Indian rosewood—a very subtle but rich contrast to the mahogany and beautiful wheat-colored torrefied Sitka spruce top. The bookmatched, 2-piece top has a beautiful grain pattern with medullary rays that add a sense of almost watery depth and a classy, not-overbearing hint of flame out at the edges. I’d imagine our review guitar will be a joy to watch age. The gold, open-gear Waverly butterbean-style tuners may be the most overtly “deluxe” appointment on the guitar. But they are a stylistically cohesive element and feel super smooth and precise.

The additions to the 000-18 that put the “modern” in this very deluxe model include enhancements that appeal to tone scientists that work at the microscopic level: Liquidmetal bridge pins and a carbon composite bridgeplate—components said to improve sustain and volume. Such benefits can be very hard to qualify without a raft of test equipment at your side. But I did sense a more immediate, sometimes explosive, response, which also seemed to expand the guitar’s already considerably dynamic range. If you’ve ever checked out a 000-18 and been at all disappointed with its capacity for fast response, this version could alter your perception. Other non-traditional elements have more tangible effects, like the asymmetric neck, which puts a little extra mass on the bass side and shifts the apex of the neck in that direction as well. The effect is subtle, especially given that the neck is a bit slim. But with its ability to offer more support for the thumb when barre chording or fretting bass notes, I felt less fatigue—and I was testing this instrument at a time when my hands were feeling like a mess. However subtle the effect, I was grateful.

Song from a Siren

There’s another reason that the 000-18 Modern Deluxe feels easy on the hands: The guitar is incredibly even in touch responsiveness and output along the whole length of the fretboard. You’re never squeezing a bit extra here or there to get a note to ring true or free of buzz. Making the connection between thought, instinct, and execution of a note or chord feels like a more fluid and effortless sequence of actions. This quality can have a real upside as you formulate or play melodic sequences, as can the OM-style 1 3/4″ nut width (most 000 guitars have a slimmer 1 5/8″ spacing).

The dynamic response is also superb. Softly plucked notes have substance, body, and complexity. And even a gentle touch with flesh on string gives individual notes blooming, ringing resonance. Approach the 000-18 Modern Deluxe with a more forceful touch and it surprises with big-time headroom and fast reactivity—the kind you more readily associate with rosewood-backed 000s and OMs and bigger bodied D-series dreadnoughts.

The Verdict

Though I tried, I didn’t hear many, if any, weaknesses in the 000-18 Modern Deluxe’s tone makeup—which is what you should expect for (gulp) $3,599. I suppose you could make a case for a sort of new-guitar antiseptic edge in some harder-plucked notes—the kind a torrefied top should help avoid. But I heard nothing that sounded like it wouldn’t mellow over time. And the dynamism of the instrument makes it easy to work around any trace elements of harsh overtones, which are very, very few. Playing a flattop that you feel at one with—ergonomically, tonally, and responsively—is a treat. The 000-18 Modern Deluxe makes it extraordinarily easy to tap into that well of sweetness.
