EVANS VE-80 VOCAL ECHO Vocoder From the original US ad:

From the original US ad:

and there's Channel B modulation invert and audio phase inversion switches to give you lots of immediate control

The JHS SD-1 is a 2 oscillator synth with a switchable LP-HP-BP resonant VCF

Frequency shift: This controls the frequency domain in which the modulation waveform operates

but overall looks very good - there's some cracking to the pick guard round the jack socket
