The problem with matched JFET phasers is that the factory has to match sets of JFETs manually, and this costs time and money. Effects has a photo of one with a full face rubber pad, covering up where the Mummy would be. I've never seen a photo of an actual version produced this way. In some EH advertisements, there is a "Ram's Head" Bad Stone shown. This is usually called the "Mummy" graphic, or V1. The original graphics feature a grotesque face. It is notable for including feedback via its "Blend" control, (later versions changed the name to "Feedback") which the earlier Maestro PS-1 and MXR Phase 90 units lacked. Release date is murky, but it is shown in 1974 advertisements. The Bad Stone began as a matched JFET based phaser, probably inspired by the Maestro PS-1. It is unknown what that graphic is, but "Mummy" is the usual description. The original Bad Stone Phase Shifter sports my favorite Electro Harmonix graphic ever.
