FINAL ASSEMBLY
AND TESTING
To install the switch, guide it
into its hole first, positioning the
body of the switch so the switch
will flip side to side and not up
and down. Once the switch is
secured, then reinstall the rest of
the components back into the
pedal housing.
Re-attach the back panel with
the four mounting screws. Plug
in your guitar and an amp, and
take your MXR Phase 90 for
a test drive. When the switch
is engaged, the pedal should
be noticeably warmer and
less harsh. If you experience
intermittent signal or other
irregularities, pull the back panel
off the pedal again and inspect
your solder joints.
