Why these settings

The Champion II 25 features a two-band EQ without a mid control, so mid is set to null while bass is cut to 4 and treble pushed to 7 to approximate Michael Schenker's mid-focused British bark. Your Les Paul Special's P-90s naturally provide gritty mid bite that complements the British voice, but slightly rolling the guitar tone to 8 rounds off P-90 brittleness. The DS-1 is set with low distortion and elevated output to act as a tight front-end drive boost into the amp's onboard crunch. For the studio cut's signature vocal nasal honk, engaging a wah pedal parked midway in its sweep provides the iconic half-cocked filter curve.

PRO TIPMichael Schenker's defining vocal lead texture relies on leaving a standard wah pedal switched on and parked roughly halfway through its forward sweep to create a resonant mid-band peak.
