Has anyone ever played one of these? The Seymour Duncan SFX-04 Twin Tube Mayhem Preamp features 2 Phillips Sylvania 6205 tubes, 3-band EQ with high and low mid switch, gain and level controls, 4 or 8 dB switchable boost, on/off and boost LED, true bypass and silent switch that eliminates switch noises.

I wrote something up for this pedal at G-V

Here is a video

Awesome. I still like the Guyatone Metal Monster better though.
