2. Just Got Paid
E StandardMeasured
Notes
The main tab plays the chopping riff and the slide part in E Standard; a second, little-viewed tab and a list on Wikipedia put the slide in open E (E B E G♯ B E). Both keep the low string on E, and TuneLit's semitone check agrees. The record sits at concert pitch.
