Hi Brent, flat wound strings are designed to reduce noise due to ones fingers or a slide/bar moving along the strings. I would imagine the reason/benefits for using them would apply with either fretted or unfretted.
I find that flatwound strings (though I have not tried them all) are not as bright sounding as wire wound strings, so without frets they may not sound very bright. If you try them let us know.
If by "fretless",, you mean still playing with finger fretting .. and wish to reduce "finger chirp " then go ahead .
But if you mean "playing with a slide" , They are kinda pointless . (you wont get " finger chirp" with a slide anyway ) and any "wind grind" is barely noticeable on a slide.
not to mention they usually sound muddy and kinda " flat " (pardon the pun ) .
So as a slider ... leave the flats for the jazz players .
Brent, I use nothing but Flatwounds on every instrument, fretted or not, from 1 to 6 strings. True they aren’t as bright, but if you want a bright sound D’Addario makes a Flatwound called Chromes, they also sound great? Keep in mind that all the great slide blues players used Flats. I have lots of old git’s & I like the old blues sound & feel, so the warmth of Flats are my preference.
"all the great slide blues players used Flats" ... ? (reaches in pocket to count the change i have to bet against . ) ....
Round wounds weren’t on the market til early 60’s, all guits came with flats before then?
Flatwound strings came relatively late to the game, marketed by La Bella in the 1940s, before then, it was all round wound.
Agreed , (unless you count catgut etc ..) . But my comment stems from an all night debate in chat on here a few years ago , where that exact line ""all the great slide blues players used Flats"" , was stated . hence the argument came up that alot of blues greats came after the invention , and naming just one would easily win any bets . (since they said """all"" )
I thought you were a part of that convo . hence the joke about digging for change .
Interesting thread. I haven't tried them, all of my builds are fretless, so far. I have two fretted Gitty necks. I have boxes... Sounds like I need a set or two of flat strings... Oh, darn! Curiosity has set in... (snicker)
I'm sick of flat strings.........every time the weather changes the strings go flat and I have to retune them. The tuning goes flat if the guitars are left out of the case.
I'm serious, I have a couple of guitars that detune themselves by the same amount, in tune but flat.
i tried flat wound strings once, didnt like them and went straight back to DÁdarios.
I would think that Flatwound strings would be fantastic on a fretless guitar or bass. I bought a set to try out, but I haven't put them on anything yet.
