Flatwound Tension

I have TI’s on my L1000 and just put LaBella LTF’s on my L2000 on Monday. Took off a set of TI PB’s for the LTF’s. What can I say, I’m a convert to flats. LTF’s are higher tension than the TI flats but still quite nice. Very easy on my 60 year old fingers. I would recommend them to someone who might be a little put off by the TI lower tension.
+1 I've been using LaBella low tension flexible flats and I think they are a terrific string. The tension is just right for me and they sound great on my P Bass.
 
These are my impressions/recollections from memory and from experience; no guarantees of accuracy:

TI JF344 - by far the lowest tension
D'Addario Chromes - fairly high
RotoSound SM77 - fairly high
GHS Precision Flats - medium
LaBella 760 FL and FX - medium
Pyramid Gold - low but not as low as TI
Fender 7150 - medium (strange gauges)
DR - no experience
Sadowski - no experience, are they Labella?
Hi.
Interesting thread .. I’ve got similar impressions as yours although I’d say that the lightest gauge Chromes strings to me have a slightly lower tension than the SM-77, but by a tad only, I guess ..
I’ve also removed a set of JF344 from on of my P-basses and installed a set of almost new SM-77.
The neck required an adjustment due to the increased strings tension, the bass’ tone became darker but punchier.
I like it .. to such an extent that I’d like now to try the LaBella 760 FL

It will be interesting to hear your comparison. I expect the FL’s may exert less tension, but haven’t played the Rotosounds in quite a while. I usually find the FL’s similar to “average” roundwounds in tension, and can go back and forth with minimal adjustment.
 
I tried three flatwound sets last week that I had great curiosity about it: TIs, SM77 and La Bella 760FS.
I was a bit surprised to found Rotos and La Bella to not be the bridge cables most people talk about.
Perfectly playable, on par with Fender stiffness that I had on a P.
I think Chromes are much stiffer than all of those; but only string so far that I found unplayable was the LB Jamerson set.

Even TI flats I didn't found that floppy (obviously the most flexible of all flats), except for the A string, that really is. Didn't cared for its tone though, glad I didn't have to buy them to discover it.

LaBella 760 FL and FX - medium
Hi TomB
There must be a difference between the two FL and FX:
FL = 043, .060, .082, .104
FX = 039, .056, .077, .096. FX seems lighter.
And even on the paper, the FX are Lighter than the JF 344 ( 043 - 056 - 070 - 100")
witch I have on two bass, and happy with them.
In term of flexibility, could you compare FX and JT ?
I am searching for the lightest gauge possible for my accoustic.
For the moment I have the JT. Have tested the LTF but find them not as fexible as the JT.
Thank's for your answer

I can’t, it’s been too long since I had any FX on a bass. My guess is that FX are firmer than the JF’s, given that Labella introduced the LTF’s to address that market. …but it’s just a guess. Others here may know more.
 
Hello folks -

I'm a recent convert to flats and have been using TI JF344s for a little over a year on one of my P-Basses. I recently tried a set of RotoSound SM-77s on a J-Bass and, while very different in tone and higher in tension, I'm liking them a lot as well. I've had a set of D'Addario Chromes (light gauge) on fretless P-Bass for a while, too and even though I like the tone, the tension is a bit high for me.

I searched for a thread that made a comparison of flats by different companies and their relative tensions. I found a lot of threads that touch on the subject a little, but none that address it straight-on.

SO: Can anyone with first-hand experience please give me your thoughts on the relative tensions of the most popular flats out there?

I'm particularly interested in:
TI JF344
D'Addario Chromes
RotoSound SM77
GHS Precision Flats
LaBella 760 FL and FX
Pyramid Gold
Fender 9050 or 7150
DR
Sadowski
If I missed any standouts, feel free to include them.

Please keep replies specific to tension and feel, NOT tone. I realize that these strings vary widely in tone, but that's covered extensively in other posts.

Please try to stick to first-hand experience.

Wherever possible, try to compare strings of similar gauge.

I understand that there is a difference in actual string tension in lbs. and perceived tension. I'm only interested in how the strings feel, ie: flexibility, stiffness etc... so, yes, this will be somewhat subjective.

I'm probably asking a lot here, but the TB community has a lot of collective experience, so I'm anxious to see what we can come up with as a group.

If this has all been covered before, my apologies. I couldn't find a direct match in a search, but feel free to link me to a thread that's already beaten this to death!

Thanks in advance -

Talking about stiffness and resistance to breaking:

1) TI JF344: low stiffness and won’t break almost ever.
2) Labella DTF 760FL: medium-high stiffness and won’t break ever.
3) Labella DTF 760FX: medium-low stiffness and won’t break ever.
4) Labella LTF 4-A: medium-low stiffness and may break.
5) Pyramid Gold 45-105: medium-high stiffness and won’t break ever.
6) Fender 45-105: high stiffness and won’t break almost ever.
7) Dunlop DFSB 45-105: very high stiffness and will likely break (worst flats ever IME).
8) Rotosound SM77: medium-low stiffness and won’t break almost ever.
9) D’Addario Chromes 45-100: medium-high stiffness and won’t break ever.

Just to prove there’s no accounting for taste, I have to weigh in that I like Dunlop flats and have never broken one :).

Why might the LTF's break?
 
Why might the LTF's break?
My observations are based on the behaviour of strings installed on one bass and then moved on to other basses in order to find the best pairing possible.
I bought two packs of LTF 4-A .. in both cases, after the second bass swap, the A string started slipping on the tuning peg, ultimately breaking ..
Same “tests” have been carried out for the other strings models i mentioned in my post above.
If you put them on a specific bass and leave them there no issues.

I use Chromes. 55-75-90-110 or 50-70-90-110 tuned down a whole step DGCF. I like these because I can buy singles to suite me. I strayed a couple years ago and tried Labella Deep Talkers and now am switching back to Chromes. I also have some Basses set up with Daddario XL Nickles in the same gauges and tuning. I have used Rotosounds and really like them but not available in singles. Ernie Ball Cobalt flats are still on my radar but I do not care for their Group 1 flats. For myself it is simplest to just stay on course with one string and make it work. This also saves me from having to replaces brass nuts and doing major setups.
 
Thank's for your input.

3) Labella DTF 760FX: medium-low stiffness and won’t break ever.
4) Labella LTF 4-A: medium-low stiffness and may break.
To your opinion, witch are the lowest stiffness ?
Thank's for your answer.
Strangely enough, in view of the meaning of LTF, those with less stiffness into them between these two are the DTF 760FL IME.

TI JF344 - by far the lowest tension

I'd pretty much agree with this, with the exception of the Rotosound SM77s; I'd rate these as very high. Rotos are known as bridge cables for a reason (I still like them, though; their tone on a T-Bird is worth it, IMO). I actually have all these on one bass or another at the moment, so I'll add;
DR - medium (a touch less than GHS's P Flats)
Sadowski - medium (the original Blue Labels, anyway)...:cool:

The SM77 I have installed on my jazz bass, with its highly sensitive neck to high tension strings, don’t feel like bridge cables at all.
Somebody in another thread suggested that they may be considered a cheaper alternative to TI JF344 and I have to substantially agree with this statement.
