It appears to have an original red Surrey Electronics case, compared to this racked one. You'll find a spec sheet there as well.

"Surrey Electronics Spectrum Shifter

Uses the same principle as Bode frequency shifter. Ostensibly for 'Howl Reduction' but capable of some very interesting effects. Essentially, unlike a pitch shifter, a frequency shifter does not preserve the harmonic relationships in the input signal. In practice this means the output quickly starts to deviate from what is going in and extra tones are added which then interact and interfere with the source producing new harmonics and drones. Very good with other fx. Great studio addition as you can plug allsorts in not just for vocals.

31cm x 27cm x 24cm
240v unit

Mono input and output via 1/4" jacks on the rear. (standard 'guitar' Jacks)
some scuffs and slider plastic is missing, did not replace as does not affect use. See photos."
