"Rare chance to get hold of one of these, in great shape & fully working!*

This is a very basic analog synth, designed by David Cockerell who designed all the coolest EH stuff & also worked on the EMS synths, of course. It has a very growly, distinctive filter! Played from the 'keys' it's good-sounding & very straightforward (no envelope!) but spend a bit of time with it, mess around with the sliders while you're playing & you'll be surprised at the 'hidden' sounds you can get.

In very good shape, & I have cleaned the slider pots. If you check the clips on Youtube, you will notice they all sound awful. I think this needs to be played as much on the sliders as the keyboard, to manually open up the filter etc. Sliders were full of crackle & stiff to move, are now smooth & crackle-free. All the slider caps are original & intact, except the tip for the On/ Off switch which is missing- purely cosmetic! The cardboard back has a little wear around the sockets, & the battery clips in perfect condition, no sign of any leaks or corrosion at all.

There's a particularly nice PWM bass sound, very reminiscent of the riff of Being Boiled (Human League), which would have been a Korg 700s, I think?


*I'm not entirely sure what the deal is with the SENS setting. There is a Piezo mic stuck underneath the touchpad, which I'm guessing might re-trigger the filter if you tap the keys(?) Again, looking at Youtube, there are videos that claim to show it working, but I'm not convinced.. as far as I can tell, the Sens setting seems to have no effect on filter or triggering or anything..

Works from 2x 9v batteries, & has an internal speaker. I think this sounds great with batteries, through the speaker! There is a 1/4" Output socket & a 1/8" socket for a PSU **I have never used this with a PSU.. being EH you'd imagine it's 18v+, & I have a suitable PSU for my Electric Mistress, but I have a feeling this may be 9vAC. The only pic I've seen of a PSU with this (on Matrixsynth) was EH-branded & 9v- tricky to find any info on this! My advice- be careful & stick to batteries!!**"
