EML ElectroComp 101 vintage analog synthesizer

via this auction

"EML ElectroComp 101 analogue duophonic synthesizer. An opportunity to own a rare vintage EML 101 in excellent original 'collectors' condition - only 1000 were made and this was originally sold on 11 November 1974 based on the log kept by ex-EML founder Dale Blake.

I bought the EML from Tone Tweakers in the USA in 2008 where it had been fully serviced. It's in extremely good condition and is all original apart from the leather handle (which I replaced with one very similar to the original), and the four rubber stick-on feet on the bottom. EML built their instruments from military grade components and they last very well.

The EML 101 has four VCOs two of which can double as an LFO. The VCOs can be swept from triangle through square to saw. It has a lovely and characterful 12db VCF which sweeps continuously from LP through BP to HP and, contrary to some reports, will self-resonante a little. It also has a great modulation control sweeping through AM to RM.

The EML 101 sounds nothing like its contemporary rivals from ARP and Moog and has a character of its own - edgy but huge, with a lot of bottom end. It's capable of duophony as well. There are lots of modulation possibilities, including S&H. It's semi-modular and audio and CV can be used interchangably when using patch cords. It's also possible to tune the EML 101 to tunings other than 12 semitones per octave.

Please note that EML used a system of 1.2v/octave (so 0.1v per semi-tone) which, apart from the lack of practical interface, means it's not compatible with any other analogue synths, but who cares when you've got four VCOs! Please also note that the EML-101 runs on US voltage (110v) so requires a step-down transformer for use in the UK/EU.

The EML 101 is built into its own wooden case and the synthesizer is attached to the keyboard by catches."
