01Donner DS-1 (Distortion)
Used as a clean boost/tightener in front of the amp to mimic the fast low-end transient of active EMG pickups
The JCM800 2203 is the exact core amp used on the record, so its preamp is dialed to provide the main crunch rather than relying entirely on the pedal. The Ibanez IBZ-6 passive pickups have softer output and slightly looser bass than the studio EMG 81, so the Donner DS-1 is set with minimal distortion and elevated level to push the input and tighten palm-mutes. Midrange is pushed to 7 to replicate the signature British punch cutting through the mix.
