Let me say I'm sold, put then on a Yamaha RBX-EW and the sound was outstanding, the tone of the guitar shifted down to very pleasant full rounded tone

Best bass strings for dull, wooden tone

Stay in tune pretty well and have a smooth, beautiful tone.

They have maintained their tone well (3 months daily playing at this point) with no appreciable loss of character

I just recently tried them on my 1973 Precision and was really surprised by the sound - very full sound with great tone.
