Right now, I'm stuck between the Transition and Gravity Storm bridges, if we are sticking to the Dimarzio brand. The Transition Bridge is quite a bit hotter than I was expecting and probably not the right fit for the guitar it's sitting in at present. Either one is very organic and great when split. Really big accomplishment for Dimarzio lately - organic and powerful.
I'm having a hard time putting the guitar with the BK Rebel Yell down at the moment, truth be told. It's about a medium + output pickup, but it's so clear and delivers harmonics and soaring leads like none other. But, back on point - I'm still curious about the classic Dimarzio SD! So many iconic tracks cut with that one, it's undeniable in the right guitar.
In the past I've used the PAF Pro (FAT and rich!), Evolution (holy treble!), Tone Zone (meh in everything I've had it in), HFH (excellent neck for single coil tones), and a handful of others. They do make some fun pickups.
