I don't put much credit in this presentation. As Mike indicated the setup should have been changed got each string gauge. But IMHO there were a number of things that would change the effect of string gauges on tonal qualities that were either just brushed over or ignored completely.

1-He used just the bridge pickup and that would produce more treble than the mid or neck pickup. If he had used each pickup individually he would have heard the different tonal qualities of those different gauges.

2-Also if had used different pick gauges he would have heard different tones.

3-Same as if he had picked in different positions, i.e. near the bridge to near or over the neck.

4-One should never use distortion when talking about tonal qualities of different string gauges.

If he had talked less he could have done all of those test.

FWIW - I have tried a number of string gauges. I will add the same string gauge from the same company will sound different on different guitars. As I said different pickups, picks, and picking all change the sound. I use 12s flat wounds down to 8 round wounds on my guitars.

YMMV
