New EB Cobalt Flats?

I put a set of EB 2810 on my sub ray5 instead EB 2816.
2810 sound very nice on my previous sub ray4 and 2816 give the Cort DLX V lot of growl and punchy tone plus useful B tone before 7th fret. But I wanna try something different.

I can't compare the tone of 2810 vs 2816 since not use in same bass..... but 2810 are stiffer than 2816 on my hand. The Cobalt B string has bounce more a bit than Group B.

2810 still less stiff than chrome.

Hmm...I didn't know they even made Cobalt flats. I've been dedicated to Rotosound Jazz Bass 77 RS77LD Monel flats for so long, I stopped looking at other strings. The RS77LDs are 45/65/85/105. I wonder how the cobalts compare?

I’ve been using both Monel and Cobalt flats (45 - 105) on two active Yamaha BB1200S basses, one with original PU, the other modded with an active EMG P/J set. Played Monels for quite some time, less experience with Cobalts yet. Both sets sound bright but well balanced, very similar in fact. Some differences:

Monel:
  • Stiffer tension
  • Smoother and softer to the touch, very slick playing feel
Cobalt:
  • Slightly brighter
  • Louder. More output and somewhat slightly dynamically limited/compressed feel
  • More flexible, not in any means floppy though
  • More sticky and grippy to the touch, stickiness goes away, grippyness stays. They feel almost roundwound-like, I started developing callouses when I switched to Cobalts
Both sets are very good, with the active preamps on the BB1200S’s it is quite possible to make them sound all but identical. For the first couple of weeks I almost gave up on the Cobalts - liked everything about them but the roundwound feel. Now I find myself playing the BB1200S with the Cobalts more.

I don’t like roundwounds at all (playing feel, fret noise, too much hi-mid harmonics, indistinct lows, floppy feel unless ridiculously thick and so on). I like tonal flexibility, playing styles from post-punk to dub to doom metal, from experimental to traditional, from clean and clear to extremely fuzzed out.

Wow! Great information here, very much appreciated, very helpful.

I love roundwounds on fretted basses, for rock fingerstyle, but on fretless I only play flats, and mostly I prefer that for less aggressive styles, like Americana, accompaniment of singer/songwriter types, etc.

I'll probably stick with the Roto 77s, based on your comparison, but I might actually give the cobalts a try on a fretted bass, and see if they meet my tonal expectations.

I never realised the Rotos seem to be regarded by people as having higher tension than others, they seem to suit me just fine. My second choice in the past was D'Addario Chromes, and before that, I tried TI Jazz Flats, but that was so long ago in the past now (16-18 years ago), that I can't really remember much other than not disliking them, but preferring the Chromes and Rotos.
 
I’ve really been loving a set of Cobalt flats on a fretless (Godin A4 Ultra). I use the .045-.100 gauge tuned down a full step to D standard. Lots of mwah, growl, sustain and articulation but nice and thick when you lay back and thumpy with some muting. My favorite flats for a fretless at the moment, after years of using TIs. I love that I can dig in with the Cobalts without nastiness yet they remain super responsive unlike duller traditional flats (the low tension of the TIs is much more touchy, particularly downtuned).
 
Meanwhile three years of use of the Cobalt flatwounds and no noticeable change; they remain bright and have kept their sustain.

Just for comparison, on another bass I have a set of Dunlop Flatwounds, which, over the course of one year, have taken a very different trajectory: They have gone from bright and articulate to smooth and chocolaty with a decent amount of thump. Not LaBella thump, mind you, but a nice balance of thump and open mids.
 
Hey everyone - I have what might be a typical question....
My 2 main basses are a G&L L2000 with stainless rounds and Fender PJ (with EMG GZR pickups) with nickel rounds. Live I play with a touch of overdrive to add thickness and presence.
Lately I've been thinking about changing to a string with a little less high end\high mids than rounds (my rounds of choice are DR Sunbeams) - and that's with tone turned down about 50%.
I tried GHS Pressurewounds - they sounded good but essentially sounded like rounds!
Could Cobalt flats get me there? How do Cobalt flats behave with some mild to medium overdrive?
