Empress Effects ParaEq - Manual (Page 11)

Advanced Configuration
Entering the advanced configuration: Unplug the power from the
ParaEq. Plug the power back in while holding down both the tap
and bypass stomp switches. The LEDs should flash momentarily to
confirm that you are in the advanced configuration.
Modifying the advanced configuration: To toggle between true
bypass and buffered bypass use the bypass stomp. The bypass led
will display which mode you are in:
LED off = true bypass(default), LED on = buffered bypass.
To toggle between normal bypass mode and independent bypass
mode use the boost stomp switch. With independent mode you can
apply boost without having the equalization engaged.
Boost LED off = normal (default), Boost LED on = independent
Exiting the advanced configuration: Hold down both the tap and
bypass stomp switches. The bypass LEDs will blink momentarily to
confirm the ParaEq has exited the advanced configuration.
