Bought a zebra TB-12 about 4 years ago for a Jackson I owned at the time. Never installed it. After recently discovering how to mod your own pickups (changing screws, magnet swaps, etc.) I swapped out the chrome filisters for black ones and swapped out the Alnico 5 for an Alnico 8 (thanks Mojotone!). Planning to install it in a Les Paul. Will update after it is done.
Update: installed the Screamin' Demon with an A8 magnet in my Agile Les Paul copy. It's name is definitely a misnomer, as the pickup is pretty tame and doesn't push the amp hard. However, it shines when amp volume and gain are turned up a little. It's very articulate, definitely has more bite than a regular PAF. It's a tad trebly, but the A8 magnet fills it in. Overall, I am happy with the decision.
