Already well established as a true "classic" synthesizer, the Oberheim OB-6 remains unbeatable in the price bracket under £2000 since 2017. The simple fact that VCOs are on board, which highlight the stark difference between digitally-controlled oscillators ( DCOs) and voltage-controlled oscillators (VCOs); its startling! Analogue heaven, no more <> no less!

This unit was sourced from Buckinghamshire/England; one owner from new. Overall condition is exemplary. Everything works 100%. Complete with perspex desksaver lid, mini-manual and mains cord. NB:- OB-6 is fitted with global-auto-voltage-select circuitry. Unit an be plugged in anywhere on this planet <> no silly external wall warts!

The OB-6 desktop module is just as powerful and easy to use as its counterpart, the OB-6 Keyboard. The module has all of the same controls as the keyboard version and provides the same immediacy and ease of use. As with the OB-6 Keyboard, all parameters are at your fingertips, with full-sized knobs and switches and a comfortable, intuitive layout.

How does it sound? Massive — just like the keyboard, because on the inside, it’s exactly the same. The same analog signal path with discrete VCOs and VCFs. The same high-quality digital effects. The same classic Oberheim sound that has been earning raves from musicians around the world.

Also added is a poly chain feature so that any two OB-6s can be paired for twelve-voice polyphony!

Two Legends. One Instrument. 1000 memory slots ( 500 presets/500 user progammable).

Both the OB-6 desktop module and OB-6 keyboard are a once-in-a-lifetime collaboration between the two most influential designers in polysynth history, Dave Smith and Tom Oberheim (see photo).The OB-6 takes the classic bold Tom Oberheim sound — with its true voltage-controlled oscillators, 2-pole filter, and amplifiers — and adds modern enhancements such as studio-quality effects, a polyphonic step sequencer, an arpeggiator, and more. No other modern analogue polysynth can boast such a pedigree or such a massive, in-your-face sonic signature.

Vintage SEM Tone

The OB-6 sound engine is inspired by Tom’s original SEM, the core of his acclaimed 4-voice and 8- voice synthesizers. It features two discrete voltage-controlled oscillators (plus sub-oscillator) per voice with continuously variable waveshapes (sawtooth and variable-width pulse, plus a triangle wave on oscillator 2). The classic Oberheim-inspired 2-pole, state-variable, resonant filter provides low-pass, high-pass, band-pass, and notch functionality. Voltage-controlled amplifiers complete the all-analogue signal path.

Dual Effects

The dual effects section provides studio-quality reverbs, delays (standard and BBD), chorus, flangers, and faithful recreations of Tom’s original phase shifter and ring modulator. While the effects themselves are digital, with 24-bit, 48 kHz resolution, a true bypass maintains a full analogue signal path.

X-Mod and Poly Step Sequencing

Also present is X-Mod, which expands the tonal palette and makes it easy to create dramatic and unconventional sounds. Modulation sources are filter envelope and oscillator 2, both with bi-polar control. Destinations include oscillator 1 frequency, oscillator 1 shape, oscillator 1 pulse width, filter cutoff, and filter mode. The polyphonic step sequencer allows up to 64 steps and up to 6 notes per step. You can create sequences polyphonically, with rests, and sync to an external MIDI clock. The full-featured arpeggiator can be synced to external MIDI clock as well. Unison mode features configurable voice count (1-6 voices), chord memory, and key modes.

Easy to Program

The knob-per-function front panel puts virtually all OB-6 functions at your fingertips. Included are 500 permanent factory programs and 500 rewritable user programs. Turning on the Manual button enables live panel mode, in which the sound of the OB-6 switches to its current front panel settings. In this state, what you see is what you hear, with 6-voice polyphony and polyphonic glide!

Klassic Keys GB are also throwing in a FREE GEM S2 synthesizer. The internal sound library is scrambled (but not useless), but if you turn the volume down, or do not connect to an amplifier, the keyboard remains highly useful as a MIDI controller, and the mod wheel and p/bend wheel will also work.
