Why these settings

The Fender Champion 40 runs on its clean channel with gain low to let the Big Muff provide the heavy low-end fuzz foundation without muddying. Running the TS9 with drive at zero and tone boosted emulates Tony Iommi's modified Rangemaster treble booster cutting through the dense low-end sludginess. The Champion 40 lacks mid and presence controls, so the 2-band EQ is dialed with boosted bass and pushed treble to retain bite.

PRO TIPTune down 1.5 steps to C# standard (C#-F#-B-E-G#-C#) and use light string tension with a firm pick attack near the bridge to get the signature loose, rattling low-end resonance.
