What, in your opinion, is the clearest sounding hum-free pickup? "Clear" may be interpreted many ways, but what I'm looking for is a pickup where all frequencies can be heard equally (even response - no cut in the treble, peak in the mids, etc) and the sound is clean (doesn't sound muffled, muted, or distorted). Pickup configuration doesn't matter... It can be a stacked-coil jazz pickup, inline split-coil jazz pickup, twinjazz pickups, dual/quad coil soapbars, MM pickups, split-coil P pickup, etc. Thanks in advance.
