Tapewound bass strings, explained: the third path to a warm low end

This week in bass news has been one long argument for warmth. Höfner was rescued so the Beatle Bass keeps its flatwound thump. Rickenbacker built a new model around a super-short scale and shipped it with flats. Fender honored James Jamerson, whose Motown tone came from heavy La Bella flatwounds he refused to swap for brighter strings. Ernie Ball's contribution to the week points the same way from a slightly different angle: a set of Tapewound Bass Strings, revealed at NAMM in January and slated to ship this summer (Ernie Ball).

Ernie Ball describes them as built for "a warm, mellow tone and a soft silky feel," constructed with a tin-plated steel core, wound in nickel-plated steel, then wrapped in a polished black nylon tape. The company says the result is "dark, smooth, and designed to emulate the subtle characteristics of a vintage upright bass," and that the nylon cuts finger noise (No Treble). That last phrase is the whole pitch, and it points at a string family most players have never put on a bass. So here is what a tapewound actually is, what it does, and who should reach for one.

Every bass string is a metal core with something wound around it. The wrap is where the three families split.

A roundwound is wound with round wire, which leaves a ridged, textured surface. That texture is what gives a roundwound its bright, zingy top end and its grip under the fingers, and it is what most basses ship with from the factory. A flatwound uses a flat ribbon of metal, polished smooth, which trades most of that brightness for a dark, even tone and kills most of the finger noise along with it. A tapewound goes one step further. It takes the metal winding and wraps it in a smooth ribbon of black nylon, so the surface your fingers slide across is plastic, not steel.

That nylon layer is the entire story. It is softer than metal, so the strings feel gentle under the hand and go nearly silent when you shift position. And because the playing surface is nylon rather than a hard alloy, a tapewound is among the kindest strings you can put on a fretless bass, where roundwounds slowly carve grooves into an unlacquered fingerboard. The construction details vary a little by brand, but the defining trait is always the same: a nylon coat over the wrap.

If you line the three families up on a dial from bright to dark, roundwounds sit at the bright end, flatwounds in the warm middle, and tapewounds at the dark end. A tapewound takes the smooth, fundamental-heavy character of a flatwound and pushes it further: even softer on top, even rounder underneath, with a thump that decays gently instead of ringing.

That is why every maker reaches for the word upright. An acoustic double bass has almost no metallic zing, just a deep, woody fundamental with a soft attack, and a tapewound is the electric string that gets closest to it. On a fretless the effect is uncanny, a warm, vocal tone that sits under a track rather than on top of it.

The tradeoff is honest and worth stating. A tapewound gives up sustain, cut, and high-end detail. It will not slap, it will not snap, and in a dense, distorted rock mix it can disappear. You are buying warmth and feel, not aggression or articulation. If you want a string that bites, this is the wrong shelf, and our flatwound versus roundwound guide covers the brighter end in full.

The fit is narrower than a roundwound, and that is the point. Tapewounds reward players who want a specific warmth.

Reggae and dub live here, where the bass is meant to be felt more than heard and the top end only gets in the way. So does a lot of jazz, especially fretless and upright-adjacent playing. Motown and classic soul sit close by, the same world where Paul McCartney and Jamerson got their thump from flats. Worship and singer-songwriter players who want the bass to stay out of the vocal range often love them. And fretless players reach for tapewounds as much for the fingerboard protection as the tone.

Who should skip them: anyone whose style leans on slap, funk pop, or bright, cutting fingerstyle, and most rock and metal players who want the string to track hard and aggressive. For those, a roundwound like the Rotosound Swing Bass 66 or the Ernie Ball Regular Slinky Bass is the honest answer. Pick the wrap for the job, not the other way around.

Read it top to bottom and the logic is simple: each step down the list trades brightness and cut for warmth and quiet. Tapewound is the far end of that trade, which is exactly why it is a specialist string and not a default. Most players never need to leave the roundwound row. The ones who do usually know precisely the sound they are chasing.

Ernie Ball's Tapewounds are not on the shelf yet. They were shown at NAMM and are due to ship this summer, with pricing still to be announced, so for now the move is to watch Ernie Ball's bass-string lineup for the listing. We will add a full review and buy page the moment they land.

If you want that warm, smooth feel today, the nearest thing already on the market is a flatwound, the next family over on the dial. The La Bella Deep Talkin' Flats are the classic warm set, and the heavier 0760M "1954 Original" is the literal Jamerson gauge. If, on the other hand, this whole article has convinced you that you actually want brightness and bite, a roundwound is your string. Here is one of each end of the dial to make the choice concrete.

There is a thread running through all of this week's bass news, and it lands on the tapewounds too: scale length. Ernie Ball is offering the set in both a short-scale version for 30 to 30.5 inch basses and long-scale versions for the standard 34 inch, with gauges of .050 to .105 short, and .050 to .105 or .060 to .115 long (Ernie Ball).

That short-scale option is not a footnote. A shorter scale already lowers string tension and warms the tone, the same physics behind the new Rickenbacker 3030 and the short-scale Höfner sound. Put a warm nylon tapewound on a short-scale bass and you are stacking two warmth levers on top of each other, which is about as far from a bright modern slap tone as a bass can get. Whether that is heaven or mud depends entirely on what you are playing. For the rest of this week's news, our June 26 briefing has the full rundown.
