Needless to say, what is already known, namely that Rotosound is a guarantee of total quality, like Thomann, which sells only quality products. These strings also cost little for the quality they offer.
Funkmaster were used by Mark King in the 90s, they weren't much considered by bass players, but believe me, they are excellent strings, ringing and soft, excellent scaling! Really superb.
These strings are useful for both funk and rock, but I also play Jazz, obviously setting the chain of instruments.
Pros: Light and soft to the touch, the sound rendering is exceptional.
Cons: personally nothing.
