EML ElectroComp 101 – Vintage Duophonic Semi-Modular Synthesizer

"From rags to riches....

The short video [at the listing] shows the starting condition of this wonderful Electrocomp EML-101 synthesizer.

We commissioned the super talented Wes Curry of Curry Cases to create this absolutely gorgeous solid walnut enclosure with all new hardware and high quality soft brown leather carrying handle.

Inside, this has had much restorative work, switches and pots have all been deep cleaned, power supply fully rebuilt and all electrolytic capacitors replaced and various other repairs to bring the synth back to 100%

The Pratt-Read keyboard has been completely stripped and rebuilt with all new key bushings. Key caps have all been treated with 'retrobrite' to bring them back to white. (Some were also replaced) the result being a good looking keybed that plays like new again.

This two piece synth clasps together to be portable, but when opening, the bottom clasps then clip back into the lid so that it becomes a desktop arrangement. with the cable extended you can also mount the two pieces upto about 3 feet apart."

A particularly nice example of this increasingly rare synth. It's in great cosmetic shape with only a few minor age related marks on the casing.

Check out the recent demo of a yellow accent one recently posted here.

"Perfectly working Drumstation - orange colorway - the first 808/909 clone! Very versatile, expansive midi control, 6 individual outs plus stereo mix, Din sync out (!)

The only difference in the versions is colorway and packaging; all drum stations are the same inside.

We don't see these often - Great box at a great price. Process those puppies!"

Teenage Engineering OP-XY // Groovebox Duties


video upload by Dexba

"It seems like using a groovebox for its intended purpose leads to better results than trying to ignore the metronome and get lost in arpeggiators and voices. Who would have guessed 😌
Anyway, I suck at this genre, I was mostly proud of the bassline and my 'discovery'!"
