hi everybody, I´ve found the combination obligato D&G and spirocore E&A works really well on my bass that has a weak E-string. the weak e-string is a phenomenom I confirmed with other strings, evah weich and medium, flexocore deluxe, obligato, innovation ultra black... when used the whole set of one string type always the E-string is muffled, dark, no punch and pitch definition, the A-string as well but much less. so now I think my combination of spiro and obligato is what I want to use, I like the obligato top strings sound and get more highs and definition from the spiro lower strings. I get very good even sound and feel from this combination when strung with _3/4 weich_ A string, but the E string is still a bit too weak. just now I have a many years old _3/4 medium_ E string on the bass (borrowed from another bass) and this is better - more volume & punch pizzicato and more clarity and pitch definition in arco. but it´s a bit too stiff for me on the left hand & too loud compared to the other strings and rougher sound arco then the A-string - so I thought ideally there would be a spirocore E-string with tension in between 3/4 weich & 3/4 medium. according to thomastik infeld website the 4/4 weich would fit my description, but I have a 102cm quite short scale bass - can I get away with this? or would this not work the way I want?
