Well, I didn't find the time and a fellow member did the test above anyway.If time permits, I'll try it as an OD pushing a Marshall or Marshall style drive channel and I'll report my findings.
So, let's share something else: a comparison between a TS-9 (drive @ zero, volume full up, tone @ noon) and the closest setting that I've found on a GuvNor: drive @ zero, volume full up, but also Mids + bass full up and treble @ 3/4... IOW: higher than I would have bet.
Frequency response below with TS in blue and Guv' in red. Would give different sounds with different guitars through different amps but "you get the picture"...
In each case, the second line (under the frequency response) shows the overall THD and suggests that the Guv' distorts more, in a "looser" way, even with drive @ 0. Not really surprising.
The TS has also more dynamics, as expected and as shown by the vertical amplitude of impulse responses:
Again, not surprising.
Oh, and... as the more recent GV2 in silver housing with concentric knobs has been evoked in one of the last answers: not the same animal than an original GV, IME. GV2's tend to add some "infrasonic" content to the tone, like the old MRX Distortion II did back in the days. It's meant to make pedals more amp like but gives mushy low end. Original GV and reissues are tighter IME/IMHO.
FWIW: what I obtain with my own pedals, if ever if can help.
EDIT in the middle of a home rehearsal, bluesy Gary Moore mode and mood: just tried the settings above in a tube pedal then in a Marshall style drive channel. And.. it didn't sound to my liking. But Drive of the Guv' @ 1/3, bass @ 11 o'clock, mids full up, treble @ 3/4 and volume cranked up work nice before already saturated hosts. More later...
