dB electro-musical X.Pressor

This is a completely analogue reverse sounding guitar pedal. I bought it when it first came out 12 years ago and I have not been able to find any information on the web about it. It works with two cables 1. audio and the other is connected to a copper pick up which cuts the signal then the pedal set at different settings 1. swell 2. filter 3.mix adjusts the sound to give you a reverse sounding effect. it also can produce a sitar kind of sound as well.

The person who designed this owned a guitar shop in south west london thats as much as I can remember and I no that not many where made. if anyone has any info on this pedal I would much appreciate any help they can give me.
