Based on the provided reference, the video discusses digitally recreating the recording chain used for the album Bleach, on which the song "About a Girl" appears. The video specifically states:
And from there all I did was take the impulse response. And put it onto that blackface twin reverb and softube. And tada. That's it I digitally recreated the exact recording chain used for bleach.
This indicates that the recording chain for Bleach, and therefore for "About a Girl", utilized a Blackface Twin Reverb amplifier and Softube plugins, which are software simulations of other effects. The video does not mention a specific pedal being used in the recording process. While Softube plugins can simulate a wide array of effects, the video focuses on the overall recording chain for Bleach and not specific pedal usage.
Therefore, the provided reference does not specify a pedal being used in the recording of "About a Girl."
