Jen SX-1000 Synthetone

Jen SX-1000 Image

The Synthetone SX-1000 is an old Italian basic mono-synth. It has a single analog DCO with three waveforms: sawtooth, square, and PWM (Pulse Width Modulation). There is an analog filter (12dB/octave) with cutoff, resonance, and LFO modulation. There is also a simple ADSR envelope for shaping your sounds. In addition there are also white/pink noise generators a glide effect and a vibrato effect. It's known for fairly stable tuning too. Probably its best sounds are the lead ones, the basses aren't that deep but it sure can scream!

What it doesn't have is MIDI, CV/Gate or any other form of control. MIDI retrofits can take care of this however. Unfortunately there is no patch memory, and there is no way around this limitation. Its knobs are boldly colored and well layed-out for easy hands-on access; but you'll need a Polaroid camera if you want to store your patch settings! Also lacking are an arpeggiator, sequencer, pitch/mod wheels, and effects. Nevertheless, this Italian vintage synth is a very cheap entry-level analog synth that has some unique sounds and characteristics worth checking out if you find one. It's been used by Future Sound of London, LFO, Nexus 21, Altern 8, Eskimos & Egypt, Fillmore, Man Machine, Tim Simenon, Broadcast, Plone, Luke Vibert, Ladytron, Prodigy and Herb Legowicz of Gusgus.

I bought one for £19 in cash generator the only problem was the pitch dial had been knocked off but you can still turn it, they didnt have a plastic bag big enough so I asked for a bin bag and I still remember how I felt walking home that day. It wouldnt work work for the first 2mins after buying it and I thought I been robbed then it suddeny sprung into life and has workked since. It has a lot of character and I love mine. limited but that can be appealing, as it made me really experiment.

A new band from London called Zulu Winter uses one to great effect but I didn't know these synths were so limited in function. I guess it's all about the right sound and they get the most from it.

A band called Kling Klang also use one for bass sound. I have owned one for a while (cost me £160) and I have found it to be the most versatile in my music, the PWM control is amazing considering its a 'cheap' synth.

@connor

I'm not sure if they actually are man. There are a few synths in that video that could potentially be Jens but they have features that mean they probably aren't. I have one of these and I'm extremely attached to it but as demonstrated by the video, with their iphone emulators, huge modular systems and wonderful italian leather jackets, Depeche Mode are into much more sophisticated things.
