Maybe you might want to give Fender's 9050L flats a try. As flats go, they are about as "middle of the road" as you can get, IME (I currently have 16 different brand/gauge/scale length flats on my many basses). Tension/stiffness is not too high - and not too low. Tone? Decent lows; good low mids/mids; and a decent high end. "Modern" flats, in other words... They break in quickly; what stickiness there is, goes away quickly. And, they'll last for years, if you keep them clean. The ones on one of my Danelectro DC59's have been on a couple of other basses; they're at least 10 years old, and going strong. To me, 9050L's sound a lot like TIJFs, but without the extreme flexibility - or the high price. Other flats you might like? The new, 3rd gen. Sadowsky Blue Label flats; Galli JF4505 Jazz Flats (you want smooth? These things feel like a solid, Teflon coated rod); or, the flats I have on my '13 T-Bird - Dogal R44 Flats. Dogal is an old Italian orchestral string company; their electric bass and guitar strings are really something. Optima also makes really nice flats - especially their RBs, which are made to duplicate the original Rickenbacker factory Maxima flats (Optima bought Maxima many years ago...). Which, of course, are what my 4003 wears... None of these strings are what you'd class as "Old School" thump monsters, but they aren't quite as mid-range focused as the Fenders, either. And none of them are particularly as high tension/stiff as, say, the Roto RS77LDs. I've used those - and liked them - but, at 241 lbs. of tension, they are the High Tension Champs. Work great with a pick, though..
Anyhow, some food for thought...![]()
Some interesting recommendations here.
I normally use Cobalt flats, love the feel, tension and tone.
As far as the Fender flats go, I used to use them, but they felt too stiff for me. But loved the tone.
Might have to revisit.
The Dogal's have caught my attention.
As well as those Maxima flats.
Sooner or later gonna have to try something.
There's been lots of others also that the gang here recommends.
I just need to pick the one I'm going to gamble on first.
