Been playing guitar 40 years and bass 6 or 7 and just found out that I know virtually nothing about about strings....ie different materials, tensions, lengths blah blah. How could something so basic to playing escape me? Anyway I have a 78 rick 4001 strung with medium flats that is a dream to play but the Rick sound is not for me so I am letting it go but love the strings and thinking of putting heavy flats on my MM SUB. I love the sound of the MM but I keep it strung with heavy high tension wound strings (don't ask). Thinking of putting heavy flats on the MM. Would I still get the same sound and action from the flats on the MM? I am pretty skint at the moment so can' t afford to go experimenting with different bass strings.

What are you trying to achieve? If I'm reading you correctly, you seem to want to put flats on the MM and yet have it sound the same as it does with rounds. That is unlikely to happen.
