Why these settings

The studio lead tone centers on an analog Octavia pushing cranked Blackface Fenders; without external pedals, engage the 'FAT' boost switch and push the Blues Junior IV preamp gain to 8 for maximum natural saturation. Set the mid control to 7 to inject the punchy body an EL84 combo needs to emulate KWS's big 6L6 Fender rig, while pulling treble down to 5 so your single coils stay smooth rather than spiky. When you add the recommended Octavia pedal, turn the FAT boost off, lower amp gain to 3, and let the pedal generate the signature octave fuzz.

PRO TIPSwitch to the Strat neck pickup, roll the tone knob back to around 7, and play above the 10th fret—this attenuates harsh fundamental highs so the analog octave overtone blooms cleanly.
