Having tried a number of different strings (D'Addario, Thomastik, etc), these are the best flatwounds I have found for my Jimmy Wilson Landing L1 short scale bass with Bartolini CB-1 humbuckers. Expected GHS quality with good tension and are 'bright' enough to cut through the mix. Unlike other strings they maintain even 'strength' across the pickups from E to G - other brands have been too loud over the E - so make playing more consistent and kinder on the ears!! I don't know what they would be like on a Mustang, Gibson SG or other short scale bass, but they are certainly excellent with bass humbuckers. Very highly recommended.
