Get the tone
This amp setting is designed to replicate Chris’ crunchy rhythm tone. The slightly high input gain setting would be overkill on a modern amp, but when used on a vintage style amp like a Vox AC30 it cranks the overall volume, causing the amp to 'break up' nicely. To achieve his creamy lead tones he would most likely have employed the fuzz box of the day: the Gibson Maestro Fuzz-Tone pedal! For best results select your bridge pickup for rhythm work, switching to the neck pickup for solos while adding distortion with a fuzz or overdrive pedal.
