Jürgen Haible JH-3200 PolyKorg Clone (a one-off, top condition)
x

  • Cosmetic condition: very good
  • Technical condition: very good
  • One-of-a-kind unit by Jürgen Haible: JH-3200 PolyKorg Clone, built in 2002/2003
  • The JH-3200 is the perfect blend of the PS-3100 (resonators) and the PS-3200 (2 VCOs per voice, memory storage / pull-out knobs / 64 memories)
  • Furthermore, the JH-3200 is a completely “unique” instrument. It features an additional (global) high-pass filter, and instead of the Korg chorus, Jürgen Haible opted for the more beautiful ARP OMNI 2 chorus, which is continuously adjustable in two intensity levels
  • The sound is slightly softer than the original character of the Korg PS series; it sounds sensational in stereo (Direct Out, Main Output), extremely lively and warm (no comparison to the – in our opinion – rather sterile-sounding new PS-3300FS)
  • It can do much more than the pad sounds in the two sound samples, but the polyphonic pads are just particularly beautiful …
  • Precise craftsmanship, high-quality hardware, weight: 30 kg
  • Full polyphony with 48 notes (C to B), MIDI connection
  • All documentation / schematics available

EEF Modular Synthesizer (a one-off, needs service)
x

  • Cosmetic condition: very good
  • Technical condition: fully functional, but requires servicing
  • A piece of synthesizer history: The EEF Modular Synthesizer is – to the best of our knowledge – a university project and, in the early 1980s, possibly the only modular synthesizer “Made in Belgium”
  • Built and played by Eric Feremans, it was used in the film “The Antwerp Killer” for the soundtrack
  • The system features 3x VCO, 2x MultiMode VCF, 3x LFO, 3x VCA, 3x ADSR, 2×8-step sequencers, a frequency counter, 2x ring modulator, a noise module, multiples, and a MIDI-CV/Gate module (added later)
  • Some of the internal modules look like “Elektor Formant” units; we don’t have any further information
  • Currently, the sound from the VCOs is distorted, which suggests an unstable power supply. However, we are not technicians and cannot assess this. All modules are functional, but the system requires servicing
  • Sound samples (with “clean-sounding” VCOs) attached …

“Es genügt, einen Ton schön zu spielen” sagte der Komponist Arvo Pärt im Jahre 2005. Diese Aussage ist ebenso einfach wie ich auch exzellent: Es braucht kein Meer an Tönen, denn entscheidend ist der Klang. Dass so mancher Vintage-Synthesizer der 70er und 80er Jahre teils unerreicht hochwertige Klänge liefert, steht außer Frage. Doch tatsächlich leben wir “heute” in einer nahezu perfekten Zeit. Einerseits hat man – mehr oder weniger – noch Zugriff auf die Vintage Analogen, andererseits wird auch bei Neugeräten die wichtige Komponente des hochwertigen Klanges wieder zunehmend berücksichtigt. Doepfer, Cwejman, Synthesizers.com, MacBeth, Moog, GRP, Studio Electronics, COTK, John Bowen und andere Hersteller bauen hervorragende Synthesizer, die den “Klassikern” in nichts nachstehen. All diesen (alten wie neuen) “großartigen” Instrumenten ist Great Synthesizers gewidmet. _________________________________________________________ In 2005 composer Arvo Pärt said: “Playing one tone really well is enough”. In other words, it is sufficient to play one tone 'beautifully'. I agree with that. All musical efforts are focused on the sound itself. Although I studied classical music (piano and drums), it’s the electronic sound that inspires me. Synthesizers are the epitome of new sounds and exciting tonal spheres. Today, many companies produce high-quality - excellent! - synthesizers: Doepfer, Cwejman, MacBeth, Moog, GRP, Synthesizers.com, COTK, Studio Electronics, John Bowen and others. It's their products I'm really interested in ... apart from Vintage Synthesizers, which I have been collecting for 20 years. Subsequent to our former websites Bluesynths and Blogasys, Peter Mahr and I have now created GreatSynthesizers. We hope you like it.
