In this video of Jamie Humphries, a Tumnus Germanium is seen on his traveling tour board. He says at 5:48:

Then we have the Tumnus. Now, I wanted to have a drive pedal because I wanted to treat this almost like my big rig so that I have a physical drive. And I also thought there was something nice and organic about having a drive before the ToneX. Now, we tested different pedals because I was a little bit worried s there's a big portion of Brian May in this gig. I'm also going to be using a Red Special or my Music Man Hybrid Red Special that has a um a treble booster built into it. So, we tested a lot of different pedals and I tried many different things and I found that having not just a clean boost, having the Tumnus really worked. I find that the Tumnus is just one of those pedals that you put it in front of anything and it sounds great.
