All sound clips are identical for each pickup on the Les Paul.  I used a TC Electronics Ditto+ looper to do this.  Loop #1 was for the Rhythm pickup (neck pickup), and Loop #2 was for the Treble / Lead (bridge) pickup.

The “dirty” sounds are due to a Heather Brown Electronicals “Blessed Mother” overdrive.  IMHO, one of the best OD pedals available.  Same as the Blues Jr settings, all the “OEM” settings for dirty are all the same, then I adjusted for the new speaker and did the dirtys again.  (giggle… “did the dirtys”)

If you just want to cut to the biggest differences, listing to the OEM speaker clips, then the Texas Heat clips particularly the Treble pickup.
