There's a Brian May Rig in KEMPER LEGENDS TRIBUTE COLLECTION done by Thomas Dill (i assume seeing rig's name) :
I don't have the device in front of me and played the player yesterday, there was no treble booster but i think this is a missed FX in the small unit.
I think on Profiler Stage, this FX should appear....
Unfortunately, these settings don't sound good with the real Red Special. Additionally, there is no Vox cabinet in this profile...
Btw, it's a pity that Michael Britt only uses this 3rd Power Switchback cabinet in most of his profiles... This makes all these profiles sound similar to each other...
