Again, suggested strings and gauges for fretless (revisited)

I'm still searching for a good replacement set of strings that my Ibanze fretless came with. The strings were not new, sounded ok, but I could see that the D'Addario ball ends were shedding their paint colors. They had to be old. And so I tried a set of Sandberg SS 40-128 strings, very similar to the gauge that the bass had when I purchased it. It was obvious from the start that they had a different, stiffer tension as I had to adjust the truss rod. I didn't have these strings on for a day except I left the G string on as the original 1st string just didn't have any oomph left. The replacement G blends well. But eventually I will have to change the strings.

With this particular bass a SR375F I seem to like lighter gauge (less tensioned) strings as it is effortless to play which I think helped with an almost immediate adaptation, having had no fretless experience before except for class cello 50 years ago.

I seem to be OK with rounds, but flats would be ok if they were the right ones. But Jaco used rounds, didn't he?
 
If you're wanting to get a Jaco sort of tone, then roundwounds would be the way to go!

I've used a variety across the board. I have mostly used, and mostly prefer, tapewounds on fretless. I had the same set of the old Fender nylon filament strings on a fretless bass for like 15 years, but those strings were discontinued long ago. :-( I use Labella tapewounds now, but I also think very highly of D'Addario tapewounds, and Rotosound as well if you want a bit deep, thuddier sort of sound.

I tend to not be super fond of flatwounds on fretless, but it depends on the specific string and the specific desired sound. They can work great.
 
DR Fatbeams. Plenty of mwah if you want it(setup) .45-.125 or the lighter set. I don't use them for fretted anymore but their flexibility makes them great for my fretless Ibby.
 
Jaco used rounds, didn't he?
yeah, but so what?! = use what you like! ;)

i like rounds on all of 'em --- i got used to them in the last century and stuck with them. i don't like flats, but i've had tapes and coated rounds that i like...but mostly rounds...and SS can be nice.

some nice "low tension" rounds are the TI jazz rounds (JR344) are very nice rounds, and i also like (for "low tension") dogal-hellborg "stranded core" rounds. both are pricey but worth it, IMO. but if i have doubts = roto 66 ultra-light-gauge sets almost always work for me.

good luck with your string search! :thumbsup:

I've been using roundwound singles to get the following

40-55-75-100-130

This is an arithmetic progression, the differences increasing/decreasing smoothly.

I found the best sizes for the difficult G and B strings and calculated the rest inbetween.
That gave me the best transition across the strings, and easiest to EQ overall.

A linear progression doesn't fit as well IMO.

Well...
Honestly? I don't know what Jaco used. And, I really don't much care. I'm not Jaco; I'll never be able to play like Jaco; and, I don't much care for the music he played, anyway. But, YES; he was an awesome player. I've just never really wanted to sound like anybody else. I have enough trouble sounding like a competent bass player, as it is... Anyhow...
I have 4 fretless basses. 2 of them came to me with flat wounds that I'm pretty satisfied with. One came with some lumpy, gnarly tape wounds that went into the trash as soon as the initial function check was done - and were eventually replaced with a set of tapes that I've used before - and like a lot. The other one came with a set of rounds that you'd expect it to come with - and, like those weird tape wounds, didn't last much past the initial function check.
I have no problem with rounds on a fretless bass - as long as it isn't my fretless bass, Or, any of my basses. My fingers are badly frostbitten, and nerve damaged from other things, too. Round wounds, to me, feel like I'm running my fingers up and down a very aggressive wood rasp. So, all but one of my 27 basses wear tapes or flats. Even my guitars wear flats... The one bass that wears rounds, wears TI JR324 Jazz Rounds; which are about as much like flats as rounds get, IMO. So...
In my admittedly limited experience with fretless basses, which flats would be "right"? I'd have to say; lighter gauge flats; preferably round core; and as flexible as you can stand. Of my fretless basses that wear flats?
- Schecter Stiletto Studio 4FL. It same from the factory with EB Group IV Flats. Don't know if they're hex- or round-core, but they are light gauge; as flexible as I think is necessary to play a fretless like it should be played; and on this active bass? Man, do they sound good. Barring some unlikely revelation, these are what this bass will always wear.
- Birdsong Fusion Lined Fretless. Unless you request something else? Birdsongs ship with D'Addario ECB82 Chromes. The 34" scale only ones. Kinda weird, since Birdsong basses are 31" scale, but... whatever. I was... skeptical... about them, as I don't like - or use - D'Addario strings, as a rule. And. I'm not a fan of Chromes, in particular. But... I like these strings - on this bass. According to Birdsong's owner, their basses - and their pickups in particular - are made to use these strings. I believe him, too. Other than being a little stiffer than I'd like the strings on a fretless bass to be? The bass plays - and sounds - marvelous... I can't really see myself replacing them with anything else...
- G&L Kiloton Lined Fretless. From their Custom shop, since it's fretless - and left handed. It came with the usual D'Addario Rounds; which, as usual, didn't last much past the initial function check. I replaced them with a set of La Bella LTF-4A Low Tension Flats. Honestly? I think these flats were MADE for a fretless bass. Smooth as silk; as flexible as you could want flats on a fretless to be - but not an iota more; and... OMG. On this bass? The sound is to die for..
So... like I said; use rounds on your fretless - by all means. Lots of people do - and really like them. I might like them, too; if they didn't kill my fingers. But, they do, so... I use flats, and tapes. My other fretless - a Canadian-made, '93 Fury Anthem lined fretless, wears tape wounds. It was built to wear them - and nothing else. When I replaced the weird, gnarly tapes it came to me with, with a set of TI Jazz Flats? I got ungodly, banshee noises out of it, that I pray to the Lord I NEVER hear again. A set of Roto TruBass 88 Tapes cured that... Now, it sounds like it was built to sound - as close to an upright bass as an electric bass guitar can get... The other 3, I can play pretty much like a fretted bass - if I want. But, the Fury Anthem? Uhh... no. It's not happy at all, unless you play it like a fretless bass. Play it like an upright fretless bass? That's what it was made for... :cool:

OK.... I'm gonna be "that guy". 2 things, nice guy first:

1) Your thinking has gotten you to the correct result - 40-55-75-100-130 is a decently balanced set. I use 40-55-70-95-130, but that's splitting hairs. So far, so good.

2) This comment makes me "that guy". Your terminology is off, which might make things confusing if we don't clear it up. What you (and I) are using in our gauges is a geometric progression - each string gauge goes up by a multiplication factor of 1.33 or so over the previous gauge. An arithmetic progression is one with a constant difference between strings - 40-60-80-100-120 for example.

A linear progression is not usually a term used in math, but if/when it is, it and an arithmetic progression are the same thing.

I prefer lighter gauged sets for fretless.

I've used:

TI Jazz Rounds
GHS Presurewounds
LaBella Copper White Nylons
Dean Markley SR2000

They all sound good on fretless.

I'm not a fan of black nylons or flats on my fretless basses. But that's just on my basses and my own personal tastes. YMMV. :)

I currently have the TIs on one bass and the Dean Markleys on another.

A recent post suggests it is an arithmetic series (not progression)
Small point, we seem to agree on the principle whatever.

When it comes to math terminology, I suggest you trust your local Physicist (I am one of those).

An arithmetic sequence (or progression) is where you add a constant to each term to get the next one. A geometric sequence (or progression) is where you multiply each term by a constant to get the next one.

An arithmetic (or geometric) series is different.

Good, a mathmatical mind.

The sequence I arrived at adds/subtacts an increasing/decreasing difference to the adjacent string. What sort of sequence is it?

I chose the best B & G strings, and selected that sequence mathmatically without regard to how they played, and tried them. The smoother transition across and along the strings was worth the change. I could expand my EQ wider

I was happy with a linear sequence for 4 string ie 45-65-85-105, but when I experimented with a 5 string, strung both high and low, linear didn't fit the extended range The best sequence seemed to be (30)-40-55-75-100-130.
Having figired this I changed to 45-60-80-105 which was also smoother..

I think marginal gains matter, particularly at the very source of the signal.
Best

How about Ernie Ball Cobalt Flats? Didn't you like them on the TRBX605, which you no longer own?
I might try them at some point. I think I have a new set and one or two used sets that I could try. I'm thinking I want a lighter gauge, but could be wrong. FWIW the EBCF's are marvelous on my P bass. I listen to recordings of gigs I've done with it and am stunned with how well it just blends.

I'm still waiting to take my fretless on its virgin gig. I was supposed to play it last Friday but got called off because the MD got covid. This Friday for sure. It won't be perfect, but the piano player likes to play over everyone else :(.
