    Does anyone know if effects loops are pre or post eq? I have a Markbass III and there is a pre/post but the manual says that's for the DI.

    Post EQ.

    It's essentially an insert between the preamp to the poweramp.

    It depends on the amp design. It's usually post-EQ but I'm pretty sure I've seen some designs where it's switchable, just as the DI is often switchable to be pre/post EQ. If the manual doesn't say, and the schematic isn't available to examine, you could always test this by.connecting two cables to the FX loop jacks. Leave the return cable disconnected, which should cut off the power amp of the Markbass, and run the FX send to the FX return of another amp, a mixer, or a home stereo input, play or otherwise run a signal through the Markbass front end, and play with the tone controls. If they do anything, the FX loop is post-EQ.
