The sample set of ten watt settings in the manual on page 7 sound good (Tweed, Edge, and Extreme modes) but Tweed and Edge really break up nicely on variac power. I came back to them after turning on full power and initially thought "where did the gain go?".
Switched back to variac and they sounded great, without any eq.
Ah, here it is, from page 33:
A lot of this stuff is right there in the manual, it just comes across as a little understated.

In Channel 1 the high end of the GAIN control produces some great “clipped clean” sounds as the Input stage gives it up and starts to saturate. These sounds are further enhanced by the 45 and 10 Watt Power Modes and the VARIAC POWER setting on the Front Panel POWER switch.
