From the vendor

The Gomorrah is an EQD Zoar Clone.

The highly interactive medium-high gain discrete distortion uses only transistors – no op amps or diodes! The Gain control on Zoar goes from the edge of break up all the way into the crunchy, grinding sound abyss. The character of the distortion is dependent on the setting of the Weight control as well as the pickup type and further fine-tuned by the EQ section. This thing ain’t coming of your board once you build it!

It will run at 18v – just make sure your caps are rated for it!
