Why these settings

To compensate for the lower-output, brighter Jaguar single coils compared to Daniel Johns' humbucker-equipped PRS, bass is boosted to 7 and the guitar tone is rolled back to 8 to tame harsh treble. The Katana 100 MkII's Lead amp type combined with the onboard Metal Zone booster captures the high-gain Soldano/Mesa wall of sound without needing external pedals. Quiet verse clean: roll guitar volume down to 6 or tap the amp panel to bypass the onboard booster.

PRO TIPFreak's signature chunk comes from heavy downpicked palm-mutes right near the bridge saddle; tune your low E down to Drop D to get the exact low-end attack heard on the record.
