Round Cores: Lower Mass?

    I have a preferences for round core strings, TI rounds, DR Sunbeams & Hibeams.

    I've noticed that round core strings have certain advantages, & of course, with something gained there is something lost. Hex cores do give you a very hard "punch in the gut" transient. Round cores sustain more, particularly Sunbeams.

    I'm told those hex cores are stiffer & have more mass. This is probably a stupid question to which there's an obvious answer but: How can hex cores have more more mass than rounds? If there are wrapped outer layers, then shouldn't the wrap around round cores be tighter, denser. Conversely, wrapping around a hex core would have eight small gaps filled with air. Duh?

    Also, I know that TIs have a buffer layer of silk & are an exception. Remarkable, considering their flexibility, they do have a surprisingly hard transient pop to them.
  2. :eyebrow: a 6-sided hexagon cored string would have 8 small gaps filled with air :confused:
    This may be the Mickey's talking but you don't make sense.

    This is where the difference between "tension" and "feel" is completely different. Until DR provides tension charts, you won't know for sure, but yes, if you have (for example) a .045 in a hex core and a .045 in a round core with everything else remaining constant, the round core on paper will have more tension. However, given the makeup of the core wires, the hex core will "feel" stiffer to your fingers.

    That's a stranded core, which is typical in classical string (read: violin family of instruments) production. Given that TI was a big name in that area, it's no wonder they adapted that tech to their electric strings when the time came (and also a reason why they are so expensive compared to others).
  4. This is a great topic to explore further. Some other factors would be core to wrap ratio and tensile strength of the raw materials.
    Similarly, I think it's a misconception that La Bellas are stiff for a flatwound. They are wound on a thinner gauge core that should result in a string with less tension than most strings which are wrapped on larger diameter cores. I'm sure someone will correct me if they think my postulations are inaccurate.

    6 sides for a hex core? You city boys & your books, learnin' , and shoes!

    Hex Core Strings: The core "bites" into the windings causing them to be stiffer in feel. This also restricts the way the string vibrates. You will notice hex core strings vibrate in a more constant direction, side to side like...

    Round Core Strings: The windings do not grip onto the core in the same way as a hex core string. They are more difficult to make because of this and the windings come free from the core in a way that causes them to sound "dead" prematurely. The strings vibrate and flex more freely which is why these strings have greater sustain and harmonics speak more clearly. Many round core string users will describe them as "floppy" and it is actually because they are vibrating more freely with less harmonics.

    In short....

    From Dean Markley:

    "NPS RoundCore Bass
    Dean Markley worked with world renowned bassist Rocco Prestia to develop the NPS RoundCore Bass Strings. NPS RoundCore are Nickel Plated Steel strings on Round Cores. This design has more mass than hex-core strings and creates total contact between the core wire and the outer wrap wire. The NPS RoundCore strings produce a fuller sound from a longer lasting string with more tone, punch and brilliance."
