The one pictured, the Metal Maniac that I have, and the Thrash Metal. It's a pretty cool system in that you can use all the same parts and change a couple of caps in the gyrators and have a new EQ and pedal. As guitar EQ trends change, you come up with a new pedal every few years! From looking at the schematics at Free Info Soc. it appears that DOD got at least 3 different pedals out of this.

It looks to have a pretty good boost in the mid-range. I'm going to remove that for a more notched sound.
