I like all kinds of pickups, and I have an ESP prototype with Duncan minis in it. It sounds good, but minis are my least favorite pickup. They have far less character than other pickups. Interesting aside re minis: The pickup was developed by Epiphone and used in a bunch of their guitars. When Gibson bought Epiphone, they got a few truckloads of upright bass bodies and necks, guitar tuners and bridges, and several large crates of the mini humbuckers. Not wanting to throw them away or re-tool the production line to use them, Gibson came up with a novel way to incorporate them into their Les Paul: punch out the top of a P90 plastic cover and drill a screw hole in each end; the mini dropped right in. And that assembly dropped into a Les Paul body routed for P90s.
