Oberheim OB-SX Analog 6 Voice Synthesizer

via this auction


"As you know this was Oberheim's preset (mine has the full 56 presets) (with some controls to alter the sound) synthesizer which took the famous sounds from it's bigger brother the OBX.and incorporated them in the SX. It is a gray version which has both CV in/out as well as Filter CV input. The CV in/out works monophonically as you would expect, but is so very handy with other CV modules from moogerfoogers to full fledged modular synths and of course anything that has CV. It also works well as a keyboard controller with my Euro modular (use it in unison mode for this) and the OB's portamento control transmits to the euro, however the pitch and mod lever do not. Every thing works on this synth and is a real joy to play, and most of all it has that huge Oberheim sound! The keyboard also has a great feel to it, and as you can see from the pictures the keys are level. The Chips (CEM) that are used on the Oberheims are worth alone more than I am asking for the unit. Also to note that the voice boards generally go for $250.00-$300.00 a piece when you can find them...(quite rare)...and this one has 6 of them, so just by the math you can see that even in just voice boards alone I am asking less for what they would sell for collectively. So you get a great CV Controller keyboard to use with other CV products, a beautifully crafted piece of musical history, but most of all a huge sounding synthesizer that only the Oberheim OBX, SX, Xa can give."
