I've been a fan of duncans for a long time..........great voicing for recording/most applications etc, but.............
because it's a 7321 made of basswood I would probably recommend dimarzio, most cool tones with baswood imo have been made with emg's or dimarzio's.
try the evo, blaze, or d-sonic.
If you really want super tight wait for the blackout (yeah they're active but from the write ups they're possibly less 'squished' than emg's)
good luck
