I recently replaced some D'Addario Chromes with Jazz Flats. Noticeably lower tension, I had to fiddle with the truss rod for a while before I could dial in the action properly again. To me, they feel much nicer, but I've always had a fairly light picking hand anyway. If you play heavy they're probably not going to be fun to play.
I've been toying with the idea of TI Jazz Flats, but I have to admit their round wound offering had completely slipped under my radar - and the example in the video posted above sounds really good.
One of my concerns with TI Jazz Flats, is the lower tension - learning that their rounds are even lower still, has me a little cautious about taking an expensive punt.
I originally switched from Super Slinky's, and Roto Swing 66 LD, to RS66L
C , for reduced tension.
I've currently got a set of D'Addario NYXL's on one of my basses (in the equivalent gauge as the RS66L
D), and they're significantly lower tension than the LD set of Roto's - in fact not that much more tension than my regular, preferred LC set.
The tension aspect is definitely something I'm mindful of with regards to a couple of my basses, being 40, and 50 years old respectively, and I get the impression that the truss rods don't have all that much adjustment before they're at their maximum (both have very low action, and I've never needed to adjust either of them in over 30 years, once I got them set where I wanted them).
Where things get confusing, is determining the difference between string tension, and
stiffness.
I confess, the reason I originally moved from LD, to LC gauge was entirely down to stiffness - I was too young to know there was a difference, or that they aren't necessarily a package deal - as it happens I got lucky.
So, with regards to TI strings, low tension sounds good from my point of view, but what I really need to know is their relative stiffness.
I mostly play with a pick, and I tend to play with a light touch - but I do need a certain stiffness.
That means that the ideal spot for striking the string on my StingRay, and Ric, is just in front of, or over the pickup. The ideal spot on my Precision is just behind the pickup, or in line with the rear edge of the pickguard.
If I try to play as much as an inch in front of the Precision's pickup, the strings are just far too floppy, and my playing goes to hell, with reduced accuracy, speed, and articulation (not a problem when playing finger style, but way out of my comfort zone with a pick).
So, my question for you, and anyone else experienced with TI flats, and also rounds : if you play between the pickup, and the bridge - is the stiffness as loose as most other round wound strings played near the end of the neck?
