IT HAS JUST BEEN FULLY SERVICED!
The following services were done, which cost me over $400! IF you find another one for less than what mine is selling for, you would then need to find someone who would work on these (which is very rare nowadays), and then who knows how much it would cost to make it fully functional??! These synths are over 40 years old, which means unless they had just been serviced, hardly any of them would be fully functional; and condition is everything.
All sliders/knobs serviced
All switches serviced
All contacts cleaned
Cleaned inside and out
This synth is one of the most amazing synths of all time! With its rich/creamy analog sounds, it is a timeless gear, and will forever be relevant, and usable in all electronic music productions. It is truly breathtaking... And for those reasons, it will forever remain a favorite. This wonder is adored by all collectors, and will ONLY go up in value!
Please feel free to ask me any questions; I will try my best to find the answers for you.
From Gear Space.com:
The Oberheim OB-1 is on my opinion one of the best looking and best sounding synths ever made. But it is very rare and no many people did have the possibility of having or even playing one. So it remains practically unknown, unmentioned, almost forgotten in every discussion about analog synths.
That said, my intention with this video was to take a look into this classic designed and classic sounding synth.
If you can get over my English (I have to choose between speaking veeeery sloooooowly or speaking at normal speed with lots of mistakes, and... I went for time saving), you may find an useful explanation of how the OB-1 works and, more important, how it sounds.
I hope you enjoy it. (I included his video above)
This small analog monophonic synthesizer strongly influenced the sound of pop music of the 1980s. The main feature that explains the popularity of OB-1 - the ability to save settings in one of eight presets.
All functional blocks are built on discrete elements (late representatives of the OB series used specialized CEM chips).
The synthesizer has two voltage controlled oscillators (VCO), each of which has an independent frequency controller, a micro-tuning, an octave switch. There are triangular and rectangular waveforms available that can be transformed by built-in converters into saw, reverse saw, meander with different duty cycles and intermediate forms.
For modulation, an LFO is provided that produces a sine or square wave. The modulation signal can be sent to the cutoff frequency of VCF or modulate (FM and PW) VCO.
The voltage controlled low-pass filter (LP VCF) has cutoff, resonance and modulation depth adjustment. There is a selection of the number of VCF stages, which allows you to obtain a slope of 12 or 24 dB per octave. A keyboard tracking mode is also provided (higher notes have a higher cutoff frequency).
OB-1 has two built-in ADSR envelope generators. One of them is dedicated to VCF, the second - to VCA.
The synthesizer got a non-dynamic keyboard with 37 keys. The "transpose" switch allows you to change the pitch within three octaves.
Pitch bend control has an original implementation - it is carried out with a lever.
OB-1 was used by Supertramp, Electronic Dream Planet, Tangerine Dream, Sky, Herbie Hancock, Rush.
