Slinkier than others, but the tone get better with time

Low tension strings, thinner gauge, pretty elastic to the point that you might be needing to adapt your playing style as for anytime you change and try new kind of strings, I guess. I have this set on my fretless and I like that they are different than the ones on the fretted one. Win-win!

nice strings!!

It has vibe, caracter, feel and sound! It is the cheapest way to get a 'new' instrument, a new sound. Not for all music style of course. Find a matching instrument and setup well. Maybe better for soft touch playing style

Excellent Choice

Used in my US Fender J bass fret less. Have tried all the rest of flats. Anything!!! Nothing compares to them. And they need a slight running-in period not like LaBella flats that they start to feel right after 2 months.

the best

a bit expensive but I love them. also they last for a lot of years

Singing flatwounds

Flatwounds with a lot of clarity and amazing sustain.

Tension is really light for flatwounds too.

The surface is smoother than roundwounds, but not as silky smooth as LaBella760FSs.

Best flatwounds ever

These flatwound have rivh sound and they are so easy to play. Being flatwounds, they last and sound for very long time.

Excellent strings

Best strings ever. Great tone, feel and tension. Keep them clean and they will last for a very long time.

Absolutely the best

I use these on my 1984 Ric 4003s, 1967 Höfner 500/1, and 2011 Fender Telecaster Bass. Absolutely perfect tones for each, and last forever.

My favourite flats. Since the strings are thinner than "Normal" you might expect to setup neck etc. but well worth it.

Simply the best flat string

Those strings are very comfortable and with great tone. They feel like the double bass Spirocore strings under the fingers. The scale is a perfect match with my expectations. E string is robust, deep and it feels vibrating with high mass, but it's very easy to play. The rest of the strings are well balanced and sweet. I mounted these strings on two different basses (fretted and fretless) after trying most of the well known and best roundwound strings (nickel, stainless steel, etc...). Give them a try, I think it's really worth.
