| If I remember correctly, any pickups in the EMG "45" series should be drop-in replacements for Cirrus 5-string and 6-string pickups, except for the little mounting tabs on the sides. Measure your pickups to make sure. If they measure 4.5" by 1.5" (not counting the mounting tabs) then any good pickups in this shape will fit. Here are some examples:
Bartolini M45 shape ("classic bass" or "deep tone")
EMG 45 series (active)
Lace BassBar 4.5
SGD ND3-45 or SW4-45
Seymour Duncan ASB2-6
Q-Tuner BL6
Have you figured out what you're going to do with the Cirrus pickups? If these are the active pickups (with a red wire and a coaxial white wire with shield) then I may be interested. I actually think they sound pretty good.
