Bartolini MK1 vs MK5 in Cort Curbow 5

I do side by side audio of the Active MK-1 pickup and the Passive MK-55 in my Cort Curbow 5 bass. This is recorded direct though my interface, no pre-amp. The onboard pre-amp is set flat (Center detent on Low, Mid, high). The MK-1 that cam on the bass was an active/powered pickup. The MK-5 is passive.
