They are hard to find! Have you tried a Chase Tone Secret Preamp? I've been using it in front of my Scorpion, and it is certainly a difference maker. It also runs at 22v like the Badgerplex.
I was at NAMM two years ago, and had the good fortune to be alone in the Friedman room early Sunday morning. I couldn't believe how great the Betty sounded with a BE OD in front of it. Just amazing.
I use mine in front of my Mojave Scorpion, and I love it. I just like the 'sauce' it adds -- really gives a cool bump to the mids that I find very cool. Heck, I only use it for that reason alone. The boost is only at about 8 o'clock.
As was mentioned above, the EP boost pedals are NOT for...
Yeah the Ampete stuff looks to be the real deal. I'm going with a 4x4, but the 8x8 isn't that much more, so I might end up just doing that. Everything from the Ampete will go into my OX Box then twin Freidman ASMs. :thumbsup:
