According to Ron Neely II "The EH Man, All-Knowing Guru of Electro-Harmonix", Sovtek built approximately 5 prototypes for an Electric Mistress in 1994.Unfortunately these never were produced and sold.
According to the part that can be identified on the pictures the Sovtek Electric Mistress V7 would probably have been similar to the Deluxe Electric Mistress V4 and V5 Reissue.

Note that the DC adapter is 12 V but it also can be run by a 9 V battery.
