Actually, I made them new with Fast Fret+Clean cloth...They stayed the same since than (I did it days ago).
Will see how it goes...
Do you guys use fast fret on double basses?
I do not used fast fret, i feel it is best for roundwound strings on electric bass, but flatwounds don't tend to benefit from it. IMO of course. Honestly i don't even use it on electric bass, never saw the need.
