Why these settings

The Fender Pro Junior IV is a single-channel, low-wattage tube amp with no mid or presence controls — it cannot reach JCM800 saturation levels on its own. The RAT2 becomes your gain source (amp stays near-clean at gain 3), replicating the Marshall's mid-forward aggression. Fender amps are naturally scooped versus Marshall's mid-hump, so the RAT's Filter at 4 (brighter setting) compensates, pushing upper-mids to match Morello's bark. Your Tele's single-coil bridge is brighter and lower-output than his Hot Rails humbucker — bass +1 from a JCM800 baseline, treble conservative at 6.

PRO TIPMorello's riff power comes from aggressive palm-muting right at the bridge saddles with the heel of your picking hand — mute hard on downbeats, release slightly on upstrokes for that rhythmic 'chunk-chunk' breathing. The tone is in the hands as much as the gear.
