I love my Scorpios, but I'm putting Entwistle neodymium pickups in to make them even louder and more aggressive in the mids. The SD pickups are good but scoop the mids a little too much for me, but I understand most people like that sound for slap. I would recommend trying different strings before modding the bass though, it's the easiest and often cheapest way of drastically altering the sound. Stainless steel strings give you a nice bright twangy sound if that's what you're after! Personal recommendations would be D'Addario Prosteel, Elites Stadium Series, and Dunlop Super Bright steels. All very nice sounding and around £15 a pack
