Why these settings

On the Champion 20, select the British '70s voice to replicate Ritchie's cranked Marshall crunch. Because the Champion 20 lacks a dedicated mid knob, set treble slightly higher at 7 to capture the signature bite of Blackmore's Hornby-Skewes booster while keeping bass at 5 to prevent the 8-inch speaker from farting out. Solo switch: flip to the neck pickup and roll guitar tone to 8 with full volume.

PRO TIPPluck the double-stop fourths using your thumb and index fingers simultaneously rather than picking with a plectrum to get the precise percussive snap and note separation of the studio take.
