Another weird one! A rotary selector selects between a four stage phaser, wah and phaser and wah combined. The latter mode is supposed to be something out of this world. Deadend Fx (who else) have a projects for this beast and as usual, don't hesitate to support these guys by bying some nifty PCBs. They also included some useful mods such a Depth control for the LFO and two trimpots to fine tune the LFO and the sweep of the wah pot. Build docs, schematic and setup guide HERE.
And HERE is the stock schematic.
