These are good flatwounds.
On the musicman stingray:
First the G string slipped from the tuning peg on first installation, which I managed to recover...
Sound is good and deep, retains some higher mids which is nice as apposed to Labella. Tension however is high, nothing surprising with flats but be mindful.
Neck relief reset might be necessary. Though not as high as rotosounds flats.
They have a matt grey look which isn't as cool as Labella, Thomastik,... Which are shinier.
After 3 months, the E string core slipped, causing the E string to buzz and loose sustain and fundamental note.
On my Ibanez SR 5 string, with Nordstrand pickups:
The blue silk winding at the ball end is a bit long and went over the saddle, so had to remove part of it.
Sound is really really good with this bass though.
As it's a hot, bright punchy bass, these flats just work nicely with it...
OVERALL: Good strings that don't have tons of character, so they work well with a very punchy bass, to tame it maybe...
