If it's not a Tubescreamer I'll give you $5.
As suspected, it is "just another" Tubescreamer.
The Bold toggle throws in a germanium diode for asymmetrical clipping, the Hollow toggle changes the frequency of the Tone control.
Otherwise it's pretty much stock values populated with dusty old components.
It's not a bad sounding pedal by any means, but there is a lot of hype (and placebo) surrounding this one.
If you like the Tubescreamer you'll probably like it... If you don't like the Tubescreamer you might want to pass.
